Matthew 5:13

Lost its savour (mwranqh). The verb is from mwro (dull, sluggish, stupid, foolish) and means to play the fool, to become foolish, of salt become tasteless, insipid ( Mark 9:50 ). It is common in Syria and Palestine to see salt scattered in piles on the ground because it has lost its flavour, "hae tint its tang" (Braid Scots), the most worthless thing imaginable. Jesus may have used here a current proverb.
