Leviticus 27:23-25

Amplified Bible

²³ then the priest shall calculate for him the amount of your valuation up to the Year of Jubilee; and the man shall give that [amount] on that day as a holy thing to the Lord. ²⁴ In the Year of Jubilee the field shall return to the one from whom it was purchased, to whom the land belonged [as his ancestral inheritance]. ²⁵ Every valuation of yours shall be in accordance with the sanctuary shekel; twenty gerahs shall make a shekel.
