Matthew Henry Commentary Proverbs 23:10-11

"Remove not the ancient landmark; And enter not into the fields of the fatherless: For their Redeemer is strong; He will plead their cause against thee." — Proverbs 23:10-11 (ASV)

The fatherless are taken under God's special protection. He is their Redeemer, who will defend them; and he is mighty, almighty.
