'Fight' in the Bible

About forty thousand armed for war went over before the Lord to the fight, to the lowlands of Jericho.

Up! make the people holy; say to them, Make yourselves holy before tomorrow, for the Lord, the God of Israel, has said, There is a cursed thing among you, O Israel, and you will give way before your attackers in the fight till the cursed thing has been taken away from among you.
