'Droplets' in the Bible

“Let my teaching drop as the rain,My speech distill as the dew,As the droplets on the fresh grassAnd as the showers on the herb.

W I sleep, but my heart is awake.A sound! My love is knocking!M Open to me, my sister, my darling,my dove, my perfect one.For my head is drenched with dew,my hair with droplets of the night.
