exodus 19:1-4
1 In the third month after the sons of Israel had gone out of the land of Egypt, on that very day they came into the wilderness of Sinai. 2 When they set out from Rephidim, they came to the wilderness of Sinai and camped in the wilderness; and there Israel camped in front of the mountain. 3 Moses went up to God, and the Lord called to him from the mountain, saying, “Thus you shall say to the house of Jacob and tell the sons 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.
