Numbers 18:14-16

Amplified Bible, Classic Edition

¹⁴ Every devoted thing in Israel [everything that has been vowed to the Lord] shall be yours.

¹⁵ Everything that first opens the womb in all flesh, which they bring to the Lord, whether it be of men or beasts, shall be yours. Nevertheless the firstborn of man you shall surely redeem, and the firstling of unclean beasts you shall redeem.

¹⁶ And those that are to be redeemed of them, from a month old shall you redeem, according to your estimate [of their age], for the fixed price of five shekels in silver, according to the shekel of the sanctuary, which is twenty gerahs.
