These verses seem to have no immediate connection with what went before; nevertheless they come in with a blessed conclusion, to ensure the faithfulness of Jehovah. What though bad men triumph and the faithful are minished, Jesus is the same, yesterday, and today, and forever. He will keep the feet of his saints, and the wicked shall be silent in darkness, for by strength shall no man prevail. 1 Samuel 2:9.
