Tobit 13:6

If ye turn to him with your whole heart, and with your whole mind, and deal uprightly before him, then will he turn unto you, and will not hide his face from you. Therefore see what he will do with you, and confess him with your whole mouth, and praise the Lord of might, and extol the everlasting King. In the land of my captivity do I praise him, and declare his might and majesty to a sinful nation. O ye sinners, turn and do justice before him: who can tell if he will accept you, and have mercy on you?
