Psalms 119:80

Let my heart be found in thy statutes
Or "perfect", and sincere: he desires that he might have a sincere regard to the ways and worship, ordinances and commands, of God; that he might have a cordial affection for them, and observe them, not in show and appearance only, but heartily as to the Lord, and in reality and truth, like an Israelite indeed, in whom there is no guile;

that I be not ashamed;
before men, conscious of guilt; or before God, at the throne of grace; where a believer sometimes is ashamed to come, not having had that regard to the statutes of the Lord he should have had, and that he might not be ashamed before him at the last day; but have confidence, having the righteousness of Christ imputed to him, and the true grace of God implanted in him; which engaged him to a regard to all his commandments.
