“the sun and the moon and the stars, all the army of heaven.” In this context, the “army of heaven” refers to the stars and planets (also thought of as “stars”) which appeared organized and thus were referred to as an “army.”
“bow down.” The common biblical way of bowing down before people or God was to fall to one’s knees and bow the upper body to the earth. It is the same Hebrew word as “worship.” [For more on bowing down, see commentary on 1 Chron. 29:20].
