Vayikra 27:26-28

Orthodox Jewish Bible

²⁶ Only the bechor of the behemah, which should be Hashem’s Bechor, no man shall set it apart as kodesh; whether it be shor (ox), or seh (sheep): it is Hashem’s.

²⁷ And if it be of a behemah hatemeiah, then he shall redeem it according to thine evaluation, and shall add a fifth part of it thereto; or if it be not redeemed, then it shall be sold according to thy evaluation.

²⁸ Nevertheless, no cherem (devoted thing), that a man shall devote unto Hashem of all that he hath, both of adam and behemah, and of the sadeh of his possession, shall be sold or redeemed; every cherem is kodesh kodashim unto Hashem.
