Numbers 28:2-4

2“Give these instructions to the people of Israel: The offerings you present as special gifts are a pleasing aroma to me; they are my food. See to it that they are brought at the appointed times and offered according to my instructions.

3“Say to the people: This is the special gift you must present to the Lord as your daily burnt offering. You must offer two one-year-old male lambs with no defects.

4Sacrifice one lamb in the morning and the other in the evening.
