Numbers 6:14

¹²in which he was consecrated to the Lord, all the days of his vow; and he shall bring a lamb of a year old for a trespass offering; and the former days shall not be reckoned, because the head of his vow was polluted.

¹³And this is the law of him that has vowed: in whatever day he shall have fulfilled the days of his vow, he shall himself bring his gift to the doors of the tabernacle of witness.

— Numbers 6:14 —

¹⁵and a basket of unleavened bread of fine flour, even loaves kneaded with oil, and unleavened cakes anointed with oil, and their meat offering, and their drink offering.

¹⁶And the priest shall bring them before the Lord, and shall offer his sin offering, and his whole burnt offering.
