26. And the Lord spoke unto Moses, saying,
27. When a bullock or a sheep or a goat is born, then it shall be seven days under the dam; and from the eighth day and thenceforth it shall be accepted for an offering on fire unto 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 unto the Lord, offer it of your own free will.
