“Forbidding us to speak to the Gentiles that they might be saved, to fill up their sins alway: for the wrath is come upon them to the uttermost.”
King James Version (KJV)
2:16 To fill up - The measure of their sins always, as they have ever done. But the vengeance of God is come upon them - Hath overtaken them unawares, whilst they were seeking to destroy others, and will speedily complete their destruction.
1Th 2:16 Forbidding us to speak to the Gentiles. Nothing created such animosity on the part of the Jews as preaching the gospel to the Gentiles. See Ac 22:21-23. To fill up their sins always. To fill the measure of their sins so full that God would reject them as a people. Compare Ge 15:16 Mt 23:32. For the wrath is come upon them to the uttermost. They were ripe for destruction. Before twenty years it came.
