for their Redeemer is strong; he will plead their cause against you.
Note, 1. The fatherless are taken under God's special protection; with him they not only find mercy shown to them (Hos 14:3) but justice done for them. He is their Redeemer, their Goel, their near kinsman, that will take their part and stand up for them with jealousy, as taking himself affronted in the injuries done to them.
Commenting on Proverbs 23:10-11
For their Redeemer is mighty,.... 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 Jer 50:34; 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.
redeemer--or avenger (Lev 25:25-26; Num 35:12), hence advocate (Job 19:25). plead . . . thee--(Compare Job 31:21; Psa 35:1; Psa 68:5).
