The Passover commemorated God’s deliverance of Israel from slavery in Egypt (see Exodus 12:1–28). This meal was thus a testimony to God’s gracious deliverance of his people. With the death of the lamb and the subsequent meal, the people of Israel were to remember that God has rescued them from his judgment. The death that they deserved for their sins was a death that someone else would pay on their behalf.
10 While the people of Israel were encamped at Gilgal, they kept the Passover on the fourteenth day of the month in the evening on the plains of Jericho.
