When did God give the Ten Commandments? (Q257)
From To Be A Christian, An Anglican Catechism
After saving his people Israel from slavery in Egypt through the Ten Plagues, the Passover sacrifice, and crossing of the Red Sea, God gave them the Ten Commandments at Mount Sinai as covenant obligations. (Exodus 6:1-8; 13:3; 14:26-31; 19:1-6; 20:1-2; Deuteronomy 5:1-5)
