Let my heart be sound ... - Hebrew, "Be perfect." See the notes at Job 1:1. The Septuagint here is "immaculate," ἄμωμος amōmos. So the Latin Vulgate. It is the expression of a desire that the heart might be pure; that there might be no improper attachment for other objects; that there might be no defect of love to God.

That I be not ashamed - See the notes at Psalm 119:6. A man has no occasion to be ashamed of a pure heart; and that which can alone keep us from being ultimately ashamed is sincerity, uprightness, and purity in the service of God.

Let my heart be sound in thy statutes - Let it be perfect - all given up to thee, and all possessed by thee.

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.

Let my heart be sound in thy statutes; that I be not ashamed.

119:80 Sound - That I may love and obey them sincerely, constantly, and universally.

80. Let my . be sound-that is, perfect, sincere.

ashamed-disappointed in my hope of salvation.

119:73-80 God made us to serve him, and enjoy him; but by sin we have made ourselves unfit to serve him, and to enjoy him. We ought, therefore, continually to beseech him, by his Holy Spirit, to give us understanding. The comforts some have in God, should be matter of joy to others. But it is easy to own, that God's judgments are right, until it comes to be our own case. All supports under affliction must come from mercy and compassion. The mercies of God are tender mercies; the mercies of a father, the compassion of a mother to her son. They come to us when we are not able to go to them. Causeless reproach does not hurt, and should not move us. The psalmist could go on in the way of his duty, and find comfort in it. He valued the good will of saints, and was desirous to keep up his communion with them. Soundness of heart signifies sincerity in dependence on God, and devotedness to him.
