(Proverbs 23:11 KJV) For their redeemer is mighty; he shall plead their cause with thee.
I listen to podcasts by Alistair Begg as part of my morning worship and preparation. The sermons I have listened to lately have a healthy dose coming from Ruth. In that book you have Boaz who ends up marrying Ruth. In the chapters moving toward that union he keeps referring to Boaz as the “kinsman redeemer”. I cannot find those two words together in any translation I have but the Hebrew basis is the word used here for “redeemer” (1350).
Part of the Jewish law provided for the weak and helpless in society. The rich were instructed to deliberately leave crops in the fields so that any poor person willing to work could gather food. Orphans and widows are given special protection. This is a reminder that God is aware when we mess with those too weak to resist. At that point He ceases to be the Advocate or Helper and becomes the prosecuting attorney.
So? We need to be careful not to take advantage of people below us on the pecking order. We need to refuse to take advantage of opportunities that are based on taking advantage of the weak. Profit is good. Illicit profit is damning.
