Does not usually denote, in Scripture, self-conceit or personal pride, 2 Peter 2:18 , but sometimes emptiness and fruitlessness, Job 7:3  Psalm 144:4  Ecclesiastes 1:1-18 . It often denotes wickedness, particularly falsehood, Deuteronomy 32:21  Psalm 4:2  24:4  119:37 , and sometimes idols and idol-worship, 2 Kings 17:15  Jeremiah 2:5  18:15  Jonah 2:8 . Compare Paul's expression, "they turned the truth of God into a lie," Romans 1:25 . "In vain," in the second commandment, Exodus 20:7 , is unnecessarily and irreverently. "Vain men," 2 Samuel 6:20  2 Chronicles 13:7 , are dissolute and worthless fellows.
