The guilt of lying


1 The Lord spoke to Moses:
2 “When someone sins and offends the Lord by deceiving his neighbor in regard to a deposit, a security, or a robbery; or defrauds his neighbor; 3 or finds something lost and lies about it; or swears falsely about any of the sinful things a person may do-4 once he has sinned and acknowledged [his] guilt-he must return what he stole or defrauded, or the deposit entrusted to him, or the lost item he found, 5 or anything else about which he swore falsely. He must make full restitution for it and add a fifth of its value to it. He is to pay it to its owner on the day he acknowledges [his] guilt. 
 
6 Then he must bring his restitution offering to the Lord: an unblemished ram from the flock, according to your valuation, as a restitution offering to the priest.  7 In this way the priest will make atonement on his behalf before the Lord, and he will be forgiven for anything he may have done to incur guilt.”
