Deuteronomy 1:41; Deuteronomy 22:5

41 Then ye answered and said unto me, We have sinned against the LORD, we will go up and fight, according to all that the LORD our God commanded us. And when ye had girded on every man his weapons of war, ye were ready to go up into the hill.

5 The woman shall not wear that which pertaineth unto a man, neither shall a man put on a woman's garment: for all that do so are abomination unto the LORD thy God.
