'Spared' in the Bible

He defeated the Moabites. He made them lie on the ground and then used a rope to measure them off. He put two-thirds of them to death and spared the other third. The Moabites became David's subjects and brought tribute.

We will come against him wherever he happens to be found. We will descend on him like the dew falls on the ground. Neither he nor any of the men who are with him will be spared alive -- not one of them!
