Deuteronomy 22:30; Deuteronomy 27:20; Deuteronomy 29:29
A man shall not take his father's wife, nor discover his father's skirt.
Cursed be he that lieth with his father's wife; because he uncovereth his father's skirt. And all the people shall say, Amen.
The secret things belong unto the LORD our God: but those things which are revealed belong unto us and to our children for ever, that we may do all the words of this law.
