Leviticus

²⁸And whether it be cow or ewe, ye shall not kill it and her young both in one day. ²⁹And when ye sacrifice a sacrifice of thanksgiving unto the Lord, ye shall sacrifice it that ye may be accepted. ³⁰On the same day it shall be eaten; ye shall leave none of it until the morning: I am the Lord. ³¹Therefore shall ye keep my commandments, and do them: I am the Lord. ³²And ye shall not profane my holy name; but I will be hallowed among the children of Israel: I am the Lord which hallow you, ³³that brought you out of the land of Egypt, to be your God: I am the Lord.
