'Formation' in the Bible

For look, I [am] going to stir up, and I [am] going to bring against Babylon a contingent of great nations from [the] land of [the] north. And they will draw up a battle formation against her, from there she will be captured. Their arrows [are] like a warrior [who has] achieved success, he does not return without success.

Draw up a battle formation at Babylon all around, all those who bend [the] bow, shoot at her. You must not spare arrows, for she has sinned against Yahweh.
