'Dew' in the Bible

You mountains of Gilboa, let there be no dew nor rain on you, neither fields of offerings; For there the shield of the mighty was vilely cast away, The shield of Saul was not anointed with oil.

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