"But if you do not drive out the inhabitants of the land from before you, then those you let remain of them will be as pricks in your eyes and as thorns in your sides, and they will harass you in the land in which you dwell.

Your brothers also, the tribe of Levi, the tribe of your father, bring near with you, that they may be joined to you, and minister to you: but you and your sons with you shall be before the tent of the testimony.

When you go to war in your land against the adversary who oppresses you, then you shall sound an alarm with the trumpets. Then you will be remembered before Yahweh your God, and you will be saved from your enemies.
