Hebrews 11:28
28 As a result of his faith, Moses told Israel's people to prepare the first Passover meal. He told them to put blood from the sacrifice round their doors. Then the angel who destroyed people came to every home. When he saw the blood, he did not kill the oldest sons in the families of Israel's people.
11:28The Passover became an important day for the Jews. They ate a special meal on this day every year. They did this to remember that God had brought them out from Egypt. They had been slaves in Egypt, and God made them free. Exodus 12 explains about the Passover.
