It was not possible to separate warfare from religion. The connection of the two was evident in many aspects of military practice. To the Jews, God was the Lord of Hosts who went before them into battle (Exo 15:3; Judg 4:14; 1 Sam 17:45; Isaiah 42:13). There was a sacred “Book of the Wars of the Lord” (Num 21:14). Before going to war, the men had to keep themselves ritually clean, not even engaging in sexual relationships (2 Sam 11:11). Health laws were involved in the commandments concerning ceremonial uncleanliness, but there were other laws in operation as well as those (Deut 13:13-14).
