Many sorrows shall be to the wicked: but he that trusts in the LORD, mercy shall surround him.
Read Chapter 32
Augustine of Hippo
AD 430
10. "Many are the scourges of the sinner:" much is he scourged, who, confessing not his sins to God, would be his own ruler. "But he that trusteth in the Lord, mercy compasseth him about" (ver. 10); but he that trusteth in the Lord, and submitteth himself to His rule, mercy shall compass him about.
Many. Sinners deserve much punishment. But if they will repent they may find mercy. (Worthington)
This may be also the declaration of God, though the prophet seem to speak in the next verse. (Berthier)
God humbles the pride of haughty monarchs, like Sennacherib and Nabuchodonosor, treating them like beasts. (Calmet)
