Exodus 29:38-42

³⁸"Now this is what you shall offer upon the altar: two lambs a year old day by day continually. ³⁹One lamb you shall offer in the morning, and the other lamb you shall offer in the evening; ⁴⁰and with the first lamb a tenth measure of fine flour mingled with a fourth of a hin of beaten oil, and a fourth of a hin of wine for a libation. ⁴¹And the other lamb you shall offer in the evening, and shall offer with it a cereal offering and its libation, as in the morning, for a pleasing odor, an offering by fire to the LORD. ⁴²It shall be a continual burnt offering throughout your generations at the door of the tent of meeting before the LORD, where I will meet with you, to speak there to you.
