Exodus 29:41-42

41Kill the other lamb in the evening. Offer it with the same gifts of food and drink as in the morning. It is a burnt offering to the Lord. Its smell pleases him.

42You and your descendants must continue to make this burnt offering as a regular offering to me, the Lord. Offer it to me at the entrance of the Tent of Meeting. I will meet with you there and I will speak to you.
