Deuteronomy 11:3-6

when he worked miracles in Egypt, making terrible things happen to the king and all his people. And when the Egyptian army chased you in their chariots, you saw the LORD drown them and their horses in the Red Sea. Egypt still suffers from that defeat! You saw what the LORD did for you while you were in the desert, right up to the time you arrived here. And you saw how the LORD made the ground open up in the middle of our camp underneath the tents of Dathan and Abiram, who were swallowed up along with their families, their animals, and their tents.
