if a man makes a vow for Yahweh or swears an oath with a binding pledge on himself, he must not render his word invalid; he must do all that went out from his mouth.

But if the man does not have a redeemer to make restitution to him for the reparation, the reparation is to be given to Yahweh for the priest, in addition to the ram of atonement by which atonement is made for him.
