7. shall not God--not unjust, but the infinitely righteous Judge.
      avenge--redeem from oppression.
      his own elect--not like this widow, the object of indifference and contempt, but dear to Him as the apple of the eye (Zec 2:8).
      cry day and night--whose every cry enters into the ears of the Lord of Sabaoth (Jas 5:4), and how much more their incessant and persevering cries!
      bear long with them--rather, "in their case," or "on their account" (as) Jas 5:7, "for it"), [GROTIUS, DE WETTE, &c.].
