'Dew' in the Bible

“O mountains of Gilboa,Let not dew or rain be on you, nor fields of offerings;For there the shield of the mighty was defiled,The shield of Saul, not anointed with oil.

So we shall come to him in one of the places where he can be found, and we will fall on him as the dew falls on the ground; and of him and of all the men who are with him, not even one will be left.
