Exodus 34:27 BBE

²⁵  No leaven is to be offered with the blood of my offering, and the offering of the Passover feast may not be kept till the morning.

²⁶  Take the first-fruits of your land as an offering to the house of the Lord your God. Let not the young goat be cooked in its mother's milk

²⁷  And the Lord said to Moses, Put all these words in writing; for on them is based the agreement which I will make with you.

²⁸  And for forty days and forty nights Moses was there with the Lord, and in that time he had no food or drink. And he put in writing on the stones the words of the agreement, the ten rules of the law.

²⁹  Now when Moses came down from Mount Sinai, with the two stones in his hand, he was not conscious that his face was shining because of his talk with God.
