“And Jethro, Moses' father in law, took a burnt offering and sacrifices for God: and Aaron came, and all the elders of Israel, to eat bread with Moses' father in law before God.”
King James Version (KJV)
18:12 And Jethro took a burnt offering for God - And probably offered it himself, for he was a priest in Midian, and a worshipper of the true God, and the priesthood was not yet settled in Israel. And they did eat bread before God - Soberly, thankfully, in the fear of God; and their talk such as became saints. Thus we must eat and drink to the glory of God; as those that believe God's eye is upon us.
