Leviticus 6:2-5

“If anyone sins and commits a breach of faith against the LORD by deceiving his neighbor in a matter of deposit or security, or through robbery, or if he has oppressed his neighbor or has found something lost and lied about it, swearing falsely—in any of all the things that people do and sin thereby— if he has sinned and has realized his guilt and will restore what he took by robbery or what he got by oppression or the deposit that was committed to him or the lost thing that he found 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.
