KJV
And if [it be] of an unclean beast, then
he shall redeem [it] according to thine estimation, and shall add a fifth
[part] of it thereto: or if it be not redeemed, then it shall be sold
according to thy estimation.
BSB
But if it is among the unclean animals, then he may redeem it according to your valuation and add a fifth of its value. If it is not redeemed, then it shall be sold according to your valuation.
