'Passover' in the Bible
Here is how you must eat it: you must be dressed for travel, your sandals on your feet, and your staff in your hand. You are to eat it in a hurry; it is the Lord’s Passover.
Then Moses summoned all the elders of Israel and said to them, “Go, select an animal from the flock according to your families, and slaughter the Passover animal.
you are to reply, ‘It is the Passover sacrifice to the Lord, for He passed over the houses of the Israelites in Egypt when He struck the Egyptians and spared our homes.’” So the people bowed down and worshiped.
The Lord said to Moses and Aaron, “This is the statute of the Passover: no foreigner may eat it.
If a foreigner resides with you and wants to celebrate the Lord’s Passover, every male in his household must be circumcised, and then he may participate; he will become like a native of the land. But no uncircumcised person may eat it.
“Do not present the blood for My sacrifice with anything leavened. The sacrifice of the Passover Festival must not remain until morning.
