If you go [to] war in your land against the enemy who attacks you, you will signal with a loud noise on the trumpets. You will be remembered {before} Yahweh your God, and you will be rescued from your enemies.

And you will say to the people, 'Sanctify yourselves tomorrow, for you will eat meat because you have wept in the ears of Yahweh, saying, "Who will feed us good meat? [It was] good for us in Egypt." Yahweh will give to you meat, and you will eat.

Moreover, bring your brothers with you, the tribe of Levi the tribe of your father, that they may be joined to you and minister [to] you, you and your sons with you before the tent of testimony.
