In the day of battle. — Literally, in the day of arms, i.e., when he was arming for fight. God covered the warrior’s head, i.e., provided the “helmet of salvation” (Isaiah 59:17). (Comp. also Psalms 60:9 : “Strength of my head.”) Others, however, follow the LXX. and Authorised Version in understanding by “day of arms” the day of battle.
