Exodus 29:41-42

41And the second lamb shalt thou offer between the two evenings; as the oblation in the morning, and as its drink-offering shalt thou offer with this, for a sweet odour, an offering by fire to Jehovah.

42It shall be a continual burnt-offering throughout your generations at the entrance of the tent of meeting before Jehovah, where I will meet with you, to speak there with thee.
