'Appoint' in the Bible

He said, "This will be the way of the king who shall reign over you: he will take your sons, and appoint them to him, for his chariots, and to be his horsemen; and they shall run before his chariots;

and he will appoint them to him for captains of thousands, and captains of fifties; and [he will set some] to plow his ground, and to reap his harvest, and to make his instruments of war, and the instruments of his chariots.
