'Dew' in the Bible

My teaching will drop like the rain, my sayings will drip like the dew, as rain drops upon the grass, and showers upon new growth.

Of Joseph he said: May the Lord bless his land with the harvest produced by the sky, by the dew, and by the depths crouching beneath;

Israel lives in safety, the fountain of Jacob is quite secure, in a land of grain and new wine; indeed, its heavens rain down dew.
