Exodus 18:12

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.

Jethro ... took a burnt offering, х `olaah (H5930) uwzbaachiym (H2077)] - a holocaust and victims. This friendly interview was terminated by a solemn religious service-the burnt offerings were consumed on the altar, and the sacrifices were offerings, used in a feast of joy and gratitude, at which Jethro, as priest of the true God, seems to have presided, and to which the chiefs of Israel were invited. This incident is in beautiful keeping with the character of the parties, and, in the spirit of it, is well worthy of the imitation of Christian friends when they meet in the present day.
