Psalms 119:80 - Joseph Benson’s Commentary on the Old and New Testaments

Let my heart be sound in thy statutes Hebrew, perfect, or entire; that I may love and obey them sincerely, constantly, and universally. That I be not ashamed Namely, for my sins, which are the only just causes of shame, and for the disappointment of my hopes following upon them. “This is a prayer necessary for all men to use at all times, but more particularly in seasons of persecution and temptation.” When there are solidity and steadfastness in grace and virtue, as opposed to the mere form of godliness, or the fair show of the hypocrite; “when internal holiness accompanies and actuates that which is external; when the word is thoroughly rooted, and faith,” working by love, “hath acquired the sovereignty over our desires, then our hearts are sound in God's statutes, and there is hope that, in the day of trial, we shall not give our brethren cause to be ashamed of us, nor be ourselves ashamed before God.” Horne.
