Yitro, Moshe' father-in-law, took a burnt offering and sacrifices for God. Aharon came with all of the elders of Yisra'el, to eat bread with Moshe' father-in-law before God.
You shall make an altar of earth for me, and shall sacrifice on it your burnt offerings and your shalom offerings, your sheep and your oxen. In every place where I record my name I will come to you and I will bless you.
