John Trapp on Job 24:21

Verſe 21. He evil intreateth the barren that beareth not] Who had more need to be comforted, then further afflicted. But Homo homini Daemon. Jacob and Elkanab loved and comforted their wives under this croſſe. The Vulgar rendreth it, He hath fed the barren, whereupon ſome expound it of wicked mens feeding Whores, and maintaining them for their pleaſure; keeping them barren, that they may keep their beauty.

And doth not good to the widow] i.e. Doth her much hurt; for not to do good, is to do evil, Mark 3.4. He hath afflicted his barren wife, and evil intreated the poor deſolate widow his mother. What marvel then if the womb forget him, &c. if his wife bewail not ſo unkind an husband, nor his mother ſo unnatural a ſon, as verſ. 30 Thus Beza here.
