Genesis 31:54

Then Jethro, Moses’ father-in-law, took a burnt offering and sacrifices for God, and Aaron came with all the elders of Israel to eat a meal with Moses’ father-in-law before God.

And they answered them and said, “He is! Behold, he is ahead of you. Hurry now, for he has come into the city today, for the people have a sacrifice on the high place today.

“As for the prince, he shall sit in it as prince to eat bread before Yahweh; he shall enter by way of the porch of the gate and shall go out by the same way.”
