'Dew' in the Bible

Ye mountains of Gilboa, let there be no dew, no rain upon you, nor fields of heave-offerings! For there the shield of the mighty was vilely cast away, The shield of Saul, as not anointed with oil.

And we shall come upon him in some place where he shall be found, and we will light upon him as the dew falls on the ground; and of him and of all the men that are with him there shall not be left so much as one.
