Exodus 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.
