Exodus 29:40

³⁸And these are the offerings which thou shalt offer upon the altar; two unblemished lambs of a year old daily on the altar continually, a constant offering.

³⁹One lamb thou shalt offer in the morning, and the second lamb thou shalt offer in the evening.

— Exodus 29:40 —

⁴¹And thou shalt offer the second lamb in the evening, after the manner of the morning offering, and according to the drink offering of the morning lamb; thou shalt offer it an offering to the Lord for a sweet-smelling savor,

⁴²a perpetual sacrifice throughout your generations, at the door of the tabernacle of witness before the Lord; wherein I will be known to thee from thence, so as to speak to thee.
