Deuteronomy 16:1 - Clarke's commentary and critical notes on the Bible

Observe the month of Abib, and keep the passover unto the LORD thy God: for in the month of Abib the LORD thy God brought thee forth out of Egypt by night. Keep the passover - A feast so called because the angel that destroyed the firstborn of the Egyptians, seeing the blood of the appointed sacrifice sprinkled on the lintels and door-posts of the Israelites' houses, passed over Them, and did not destroy any of their firstborn. See the notes on Exodus 12:2, and Exodus 12:3 (note), etc.
