Rashi on I Samuel
Shaul disguised himself. He changed his clothes, and similarly, 'disguise yourself [הִתְחַפֵּשׂ] and come into battle,'6II Melochim 22:30. and similarly, 'its intensity makes me change [יׅתְחַפֵּשׂ] my clothing.'7Iyov 30:18. And so did Targum Yonoson render, 'and Shaul changed.'
Rashi on I Samuel
