E. whether this remark refers also to כעל ישלם, and explains it to mean like a man (who is zealous) for revenge, or is limited to כעל גמלות; in that case the whole phrase is to be translated, Like a man (who is zealous) for repaying, so he (is clad with zeal) for revenge. A. V., According to their deeds, accordingly he will repay. Fury to his adversaries, etc. He will repay fury to his adversaries, etc.
Rashi
