Leviticus 6:5

or anything about which he has sworn falsely , he shall restore it in full and shall add a fifth to it , and give it to him to whom it belongs on the day he realizes his guilt .

or whatever it was they swore falsely about. They must make restitution in full, add a fifth of the value to it and give it all to the owner on the day they present their guilt offering.

Or all that about which he hath sworn falsely; he shall even restore it in the principal, and shall add the fifth part more thereto, and give it unto him to whom it appertaineth, in the day of his trespass offering.
