Exodus 12:37-50

That night the people of Israel left Rameses and started for Succoth. There were about 600,000 men, plus all the women and children. A rabble of non-Israelites went with them, along with great flocks and herds of livestock. For bread they baked flat cakes from the dough without yeast they had brought from Egypt. It was made without yeast because the people were driven out of Egypt in such a hurry that they had no time to prepare the bread or other food. The people of Israel had lived in Egypt for 430 years. In fact, it was on the last day of the 430th year that all the LORD’s forces left the land. On this night the LORD kept his promise to bring his people out of the land of Egypt. So this night belongs to him, and it must be commemorated every year by all the Israelites, from generation to generation. Then the LORD said to Moses and Aaron, “These are the instructions for the festival of Passover. No outsiders are allowed to eat the Passover meal. But any slave who has been purchased may eat it if he has been circumcised. Temporary residents and hired servants may not eat it. Each Passover lamb must be eaten in one house. Do not carry any of its meat outside, and do not break any of its bones. The whole community of Israel must celebrate this Passover festival. “If there are foreigners living among you who want to celebrate the LORD’s Passover, let all their males be circumcised. Only then may they celebrate the Passover with you like any native-born Israelite. But no uncircumcised male may ever eat the Passover meal. This instruction applies to everyone, whether a native-born Israelite or a foreigner living among you.” So all the people of Israel followed all the LORD’s commands to Moses and Aaron.
