Exodus 13:1-10 All the firstborn, both man and beast is the Lord’s. The 1st month is named, Abib, which is the month they left Egypt in order to enter the land of Canaan promised to Abraham. Moses reminded the people of the ordinance of the Passover and the Feast of Unleavened Bread that it should be celebrated every year as a memorial when the Lord, with a strong hand, delivered them from Egypt, out of the house of slavery.
Exodus 13:11-16 As soon as they enter Canaan, they will at that time practice the ordinance of setting apart to the Lord all the firstborn that opens the womb. All the male firstborn of animals shall be the Lord’s. They shall redeem the firstborn of a donkey with a lamb, if not, then they must break its neck. Every firstborn of man among their sons they shall redeem also by sacrificing a lamb. And why is this done? Because by a strong hand the Lord brought them out of Egypt and Lord killed the firstborn of Egypt, man and animal. Therefore they sacrifice to the Lord all the males that first open the womb, but all the firstborn of their sons they redeem.
Exodus 13:17-18 God did not lead them out of Egypt through the land of the Philistines out of fear that if they saw war too soon, they would want to return to Egypt. Instead, the Lord led the people around by the way of the wilderness toward the Red Sea.
Exodus 13:19-22 Moses took the bones of Joseph with him as Joseph asked them to do. They camped at Etham on the edge of the wilderness. The Lord protected them as they travelled by a pillar of cloud to lead them by day, and by night a pillar of fire continually, throughout their journey.
Notes: Some 360 years earlier he had foreseen the day when God would bring about the exodus, and his instructions about his bones being carried to the Promised Land indicated just how certain he was of Israel’s departure for Canaan (cf. Gen. 50:24–26; Heb. 11:22). After the years of wilderness wanderings, Joseph’s remains reached their final resting place in Shechem (Josh. 24:32).
