Clarke's Bible Commentary - Proverbs 23:11
Verse 11. lFor their redeemer is mighty ] µlag goalam, their kinsman. The word means the person who has a right, being next in blood, to redeem a field or estate, alienated from the family, to avenge the blood of a murdered relative, by slaying the murderer; and to take to wife a brother's widow, who had died childless, in order to preserve the family. The strength here mentioned refers to the justness of his claim, the extent of his influence, and the powerful abettors of such a cause. But in reference to the orphans here mentioned, they having no kinsman, God takes up, vindicates, and avenges their cause.
John Gill's Bible Commentary
Ver. 11. For their Redeemer [is] mighty , etc.] As he must needs be, since the Lord of hosts is his name; who sympathizes with them, has mercy on them, is their father, and their friend; (see Jeremiah 50:34) ( Hosea 14:3 Psalm 68:5); he shall plead their cause with thee ; or “against thee”, as the Vulgate Latin version; and will certainly carry it for them, and against thee; for, when he undertakes a cause, he pleads it thoroughly.
Matthew Henry Commentary
Verses 10, 11 - The fatherless are taken under God's special protection. He is their Redeemer, who will take their part; and he is mighty, almighty.
