'Prepare' in the Bible

Then Manoah said to the angel of the Lord, “Please let us detain you so that we may prepare a young goat for you.”

The angel of the Lord said to Manoah, “Though you detain me, I will not eat your food, but if you prepare a burnt offering, then offer it to the Lord.” For Manoah did not know that he was the angel of the Lord.
