17 All the congregation of the people of Israel moved on from the wilderness of Sin by stages, according to the commandment of the LORD, and camped at Rephidim, but there was no water for the people to drink. 2 Therefore the people quarreled with Moses and said, “Give us water to drink.” And Moses said to them, “Why do you quarrel with me? Why do you test the LORD?” 3 But the people thirsted there for water, and the people grumbled against Moses and said, “Why did you bring us up out of Egypt, to kill us and our children and our livestock with thirst?” 4 So Moses cried to the LORD, “What shall I do with this people? They are almost ready to stone me.” 5 And the LORD said to Moses, “Pass on before the people, taking with you some of the elders of Israel, and take in your hand the staff with which you struck the Nile, and go. 6 Behold, I will stand before you there on the rock at Horeb, and you shall strike the rock, and water shall come out of it, and the people will drink.” And Moses did so, in the sight of the elders of Israel. 7 And he called the name of the place Massah and Meribah, because of the quarreling of the people of Israel, and because they tested the LORD by saying, “Is the LORD among us or not?”

8 Then Amalek came and fought with Israel at Rephidim. 9 So Moses said to Joshua, “Choose for us men, and go out and fight with Amalek. Tomorrow I will stand on the top of the hill with the staff of God in my hand.” 10 So Joshua did as Moses told him, and fought with Amalek, while Moses, Aaron, and Hur went up to the top of the hill. 11 Whenever Moses held up his hand, Israel prevailed, and whenever he lowered his hand, Amalek prevailed. 12 But Moses’ hands grew weary, so they took a stone and put it under him, and he sat on it, while Aaron and Hur held up his hands, one on one side, and the other on the other side. So his hands were steady until the going down of the sun. 13 And Joshua overwhelmed Amalek and his people with the sword.

14 Then the LORD said to Moses, “Write this as a memorial in a book and recite it in the ears of Joshua, that I will utterly blot out the memory of Amalek from under heaven.” 15 And Moses built an altar and called the name of it, The LORD Is My Banner, 16 saying, “A hand upon the throne of the LORD! The LORD will have war with Amalek from generation to generation.”

18 Jethro, the priest of Midian, Moses’ father-in-law, heard of all that God had done for Moses and for Israel his people, how the LORD had brought Israel out of Egypt. 2 Now Jethro, Moses’ father-in-law, had taken Zipporah, Moses’ wife, after he had sent her home, 3 along with her two sons. The name of the one was Gershom (for he said, “I have been a sojourner in a foreign land”), 4 and the name of the other, Eliezer (for he said, “The God of my father was my help, and delivered me from the sword of Pharaoh”). 5 Jethro, Moses’ father-in-law, came with his sons and his wife to Moses in the wilderness where he was encamped at the mountain of God. 6 And when he sent word to Moses, “I, your father-in-law Jethro, am coming to you with your wife and her two sons with her,” 7 Moses went out to meet his father-in-law and bowed down and kissed him. And they asked each other of their welfare and went into the tent. 8 Then Moses told his father-in-law all that the LORD had done to Pharaoh and to the Egyptians for Israel’s sake, all the hardship that had come upon them in the way, and how the LORD had delivered them. 9 And Jethro rejoiced for all the good that the LORD had done to Israel, in that he had delivered them out of the hand of the Egyptians.

10 Jethro said, “Blessed be the LORD, who has delivered you out of the hand of the Egyptians and out of the hand of Pharaoh and has delivered the people from under the hand of the Egyptians. 11 Now I know that the LORD is greater than all gods, because in this affair they dealt arrogantly with the people.” 12 And Jethro, Moses’ father-in-law, brought a burnt offering and sacrifices to God; and Aaron came with all the elders of Israel to eat bread with Moses’ father-in-law before God.

13 The next day Moses sat to judge the people, and the people stood around Moses from morning till evening. 14 When Moses’ father-in-law saw all that he was doing for the people, he said, “What is this that you are doing for the people? Why do you sit alone, and all the people stand around you from morning till evening?” 15 And Moses said to his father-in-law, “Because the people come to me to inquire of God; 16 when they have a dispute, they come to me and I decide between one person and another, and I make them know the statutes of God and his laws.” 17 Moses’ father-in-law said to him, “What you are doing is not good. 18 You and the people with you will certainly wear yourselves out, for the thing is too heavy for you. You are not able to do it alone. 19 Now obey my voice; I will give you advice, and God be with you! You shall represent the people before God and bring their cases to God, 20 and you shall warn them about the statutes and the laws, and make them know the way in which they must walk and what they must do. 21 Moreover, look for able men from all the people, men who fear God, who are trustworthy and hate a bribe, and place such men over the people as chiefs of thousands, of hundreds, of fifties, and of tens. 22 And let them judge the people at all times. Every great matter they shall bring to you, but any small matter they shall decide themselves. So it will be easier for you, and they will bear the burden with you. 23 If you do this, God will direct you, you will be able to endure, and all this people also will go to their place in peace.”

24 So Moses listened to the voice of his father-in-law and did all that he had said. 25 Moses chose able men out of all Israel and made them heads over the people, chiefs of thousands, of hundreds, of fifties, and of tens. 26 And they judged the people at all times. Any hard case they brought to Moses, but any small matter they decided themselves. 27 Then Moses let his father-in-law depart, and he went away to his own country.

19 On the third new moon after the people of Israel had gone out of the land of Egypt, on that day they came into the wilderness of Sinai. 2 They set out from Rephidim and came into the wilderness of Sinai, and they encamped in the wilderness. There Israel encamped before the mountain, 3 while Moses went up to God. The LORD called to him out of the mountain, saying, “Thus you shall say to the house of Jacob, and tell the people of Israel: 4 ‘You yourselves have seen what I did to the Egyptians, and how I bore you on eagles’ wings and brought you to myself. 5 Now therefore, if you will indeed obey my voice and keep my covenant, you shall be my treasured possession among all peoples, for all the earth is mine; 6 and you shall be to me a kingdom of priests and a holy nation.’ These are the words that you shall speak to the people of Israel.”

7 So Moses came and called the elders of the people and set before them all these words that the LORD had commanded him. 8 All the people answered together and said, “All that the LORD has spoken we will do.” And Moses reported the words of the people to the LORD. 9 And the LORD said to Moses, “Behold, I am coming to you in a thick cloud, that the people may hear when I speak with you, and may also believe you forever.”

When Moses told the words of the people to the LORD, 10 the LORD said to Moses, “Go to the people and consecrate them today and tomorrow, and let them wash their garments 11 and be ready for the third day. For on the third day the LORD will come down on Mount Sinai in the sight of all the people. 12 And you shall set limits for the people all around, saying, ‘Take care not to go up into the mountain or touch the edge of it. Whoever touches the mountain shall be put to death. 13 No hand shall touch him, but he shall be stoned or shot; whether beast or man, he shall not live.’ When the trumpet sounds a long blast, they shall come up to the mountain.” 14 So Moses went down from the mountain to the people and consecrated the people; and they washed their garments. 15 And he said to the people, “Be ready for the third day; do not go near a woman.”

16 On the morning of the third day there were thunders and lightnings and a thick cloud on the mountain and a very loud trumpet blast, so that all the people in the camp trembled. 17 Then Moses brought the people out of the camp to meet God, and they took their stand at the foot of the mountain. 18 Now Mount Sinai was wrapped in smoke because the LORD had descended on it in fire. The smoke of it went up like the smoke of a kiln, and the whole mountain trembled greatly. 19 And as the sound of the trumpet grew louder and louder, Moses spoke, and God answered him in thunder. 20 The LORD came down on Mount Sinai, to the top of the mountain. And the LORD called Moses to the top of the mountain, and Moses went up.

21 And the LORD said to Moses, “Go down and warn the people, lest they break through to the LORD to look and many of them perish. 22 Also let the priests who come near to the LORD consecrate themselves, lest the LORD break out against them.” 23 And Moses said to the LORD, “The people cannot come up to Mount Sinai, for you yourself warned us, saying, ‘Set limits around the mountain and consecrate it.’” 24 And the LORD said to him, “Go down, and come up bringing Aaron with you. But do not let the priests and the people break through to come up to the LORD, lest he break out against them.” 25 So Moses went down to the people and told them.
