Les explains that Exodus chapter 19 opens with the third month, which he identifies as the month of June. At that time the children of Israel were going forth out of the land of Egypt, and the same day they came to the wilderness of Sinai. They had departed from Rephidim, come to the desert, and pitched in the wilderness, camping before the mount. Then Moses went up into the mount unto God, and the Lord called to him out of the mountain, telling him to speak to the house of Jacob and the children of Israel. God reminded them how He had dealt with the Egyptians, drowning them in the Red Sea, and how He bore them on eagles' wings and brought them unto Himself.
