Leviticus - ESV

You shall not hate your brother in your heart, but you shall reason frankly with your neighbor, lest you incur sin because of him. You shall not take vengeance or bear a grudge against the sons of your own people, but you shall love your neighbor as yourself: I am the Lord.

When he realizes his guilt in any of these and confesses the sin he has committed.

You shall be holy to me, for I the Lord am holy and have separated you from the peoples, that you should be mine.

Six days shall work be done, but on the seventh day is a Sabbath of solemn rest, a holy convocation. You shall do no work. It is a Sabbath to the Lord in all your dwelling places.

If anyone sins, doing any of the things that by the Lord's commandments ought not to be done, though he did not know it, then realizes his guilt, he shall bear his iniquity.

So you shall keep my commandments and do them: I am the Lord.

You shall keep my Sabbaths and reverence my sanctuary: I am the Lord.

If you walk in my statutes and observe my commandments and do them, then I will give you your rains in their season, and the land shall yield its increase, and the trees of the field shall yield their fruit.
