Psalms 55:21 Smoother than cream were the speeches of his mouth, but his heart was war; his words were softer than oil, yet were they keen-edged swords. (JPS)
Micah 5:6 And they shall waste the land of Assyria with the sword, and the land of Nimrod with the keen-edged sword; and he shall deliver us from the Assyrian, when he cometh into our land, and when he treadeth within our border. (JPS)
