Matthew Henry's Complete Bible Commentary

Verse 80

Here is, 1. David’s prayer for sincerity, that his heart might be brought to God’s statutes, and that it might be sound in them, not rotten and deceitful, that he might not rest in the form of godliness, but be acquainted with the subject to the power of it,—that he might be hearty and constant in religion, and that his soul might be in health. 2. His dread of the consequences of hypocrisy: That I be not ashamed. Shame is the portion of hypocrites, either here, if it be repented of, or hereafter, if it be not: “Let my heart be sound, that I fall not into scandalous sin, that I fall not quite off from the ways of God, and so shame myself. Let my heart be sound, that I may come boldly to the throne of grace, and may lift up my face without spot at the great day.” MHBCC 598.71
