Numbers 28:16-19, 27

“The Passover  to the LORD comes in the first month, on the fourteenth day of the month. On the fifteenth day of this month there will be a festival; unleavened bread is to be eaten for seven days. On the first day there is to be a sacred assembly; you are not to do any daily work.  Present a food offering, a burnt offering to the LORD: two young bulls, one ram, and seven male lambs a year old. Your animals are to be unblemished.

Present a burnt offering as a pleasing aroma to the LORD: two young bulls, one ram, and seven male lambs a year old
