Adam Clarke's Bible Commentary Verse 8. Good and upright is the Lord ] He is good in his nature, and righteous in his conduct.
Therefore will he teach sinners ] Because he is good, he will teach sinners, though they deserve nothing but destruction: and because he is right, he will teach them the true way.
Matthew Henry Commentary
Verses 8-14 - We are all sinners; and Christ came into the world to save sinners, to teach sinners, to call sinners to repentance. We value a promise by the character of him that makes it; we therefore depend upon God' promises. All the paths of the Lord, that is, all his promises and all his providences, are mercy and truth. In all God's dealings his people may see his mercy displayed, and his word fulfilled, whateve afflictions they are now exercised with. All the paths of the Lord ar mercy and truth; and so it will appear when they come to their journey's end. Those that are humble, that distrust themselves, an desire to be taught and to follow Divine guidance, these he will guid in judgment, that is, by the rule of the written word, to find rest for their souls in the Saviour. Even when the body is sick, and in pain the soul may be at ease in God.
