יַחְפְּר֣וּ בָ֭עֵמֶק וְיָשִׂ֣ישׂ בְּכֹ֑חַ יֵ֝צֵ֗א לִקְרַאת־נָֽשֶׁק׃
He paweth in the valley, and rejoiceth in his strength; He goeth out to meet the clash of arms.
Rashi on Job
They spy in the valley Heb. יחפרו, like (Deut. 1:22), “that they may spy out (ויחפרו) the land for us,” for it is the habit of the horsemen to lie in wait in the valleys and in the ravines.
Rashi on Job
and rejoices with strength The horse rejoices and goes forth toward the weapons.
