103:6-8 Verse 6 is a topic sentence that introduces what follows. Verses 7 and 8 describe God's dealings with Israel at Mt. Sinai. The fact that God revealed Himself to Moses and the Israelites indicates His great compassion and grace. Verse 8 quotes Exodus 34:6. It restates four great characteristics about God.
103:9-12 These verses illustrate the truth of verse 8. God's compassion is clear in that He does not constantly accuse or antagonize us even though we constantly sin (cf. Eph. 6:4). He is slow to anger and He does not maintain His anger constantly. His gracious character is obvious in that He does not punish us for our sins immediately or completely as we deserve. He does not pay us back what we deserve either. His loyal love (Heb. hesed) with those who fear Him is as limitless as the sky. Furthermore He separates the guilt of our sins from us completely.
Many students of verse 12 have noted that if someone travels north or south he finally arrives at a pole from which he can proceed no farther north or south. However if someone travels east or west, he never reaches such a point. God did not say he forgives our sins as far as the North is from the South but as far as the East is from the West, namely infinitely.
103:13-18 God's compassion is father-like in that He is mindful of our finite creature limitations.
"He knows us even better than we know ourselves."166
Verses 15 and 16 beautifully describe the transitory nature of human life. It is both frail and short-lived. In contrast God's loyal love to those who fear Him abides strong forever. It transcends generations and continues on to the descendents of those who obey His law (vv. 17-18; cf. Exod. 20:5-6).
