Leviticus 27:13

But if he will at all redeem it, then he shall add a fifth part thereof unto thy estimation.

But if he will indeed redeem it, then he shall add the fifth part of it to its valuation.

But if he will indeed redeem it, then he shall add the fifth part thereof unto thy estimation.

and if he really redeem it, then he hath added its fifth to thy valuation.

If, however, the owner decides to redeem the animal, he must add a fifth to its value.
