'Quench' in the Bible

Behold, the whole family has risen against your handmaid, and they say, 'Deliver him who struck his brother, that we may kill him for the life of his brother whom he killed, and so destroy the heir also.' Thus they would quench my coal which is left, and would leave to my husband neither name nor remainder on the surface of the earth."

But Abishai the son of Zeruiah helped him, and struck the Philistine, and killed him. Then the men of David swore to him, saying, "You shall go no more out with us to battle, that you don't quench the lamp of Israel."
