"'This is the law of the Nazirite who vows his offering to the LORD in accordance with his separation, in addition to whatever else he can afford. He must fulfill the vow he has made, according to the law of the Nazirite.'"Catholic Public Domain Version
This is the law of the Nazarite, when he has vowed his oblation to the Lord in the time of his consecration, aside from those things which his hand shall find. According to what he had vowed in his mind, so shall he do, to the perfection of his sanctification.
