26. And the LORD spoke to Moses, saying,
27. When a bullock, or a sheep, or a goat is brought forth, then it shall be seven days under the dam; and from the eighth day and thenceforth it shall be accepted for an offering made by fire to the LORD.
28. And whether it is cow, or ewe, ye shall not kill it and her young both in one day.
29. And when ye will offer a sacrifice of thanksgiving to the LORD, offer it at your own will.
