Exodus

And Moses and Aaron went and gathered together all the elders of the children of Israel:

And Aaron spake all the words which the Lord had spoken unto Moses, and did the signs in the sight of the people.

Go, and gather the elders of Israel together, and say unto them, The Lord God of your fathers, the God of Abraham, of Isaac, and of Jacob, appeared unto me, saying, I have surely visited you, and seen that which is done to you in Egypt:

Then Moses called for all the elders of Israel, and said unto them, Draw out and take you a lamb according to your families, and kill the passover.
