'Drop' in the Bible

You will have olive trees throughout your territory but you will not anoint yourselves with the oil, because your olives will drop off.

“Let my teaching drop as the rain,My speech distill as the dew,As the light rain upon the tender grass,And as the spring showers upon the herb.

“So Israel dwells in safety and security,The fountain of Jacob alone and secluded,In a land of grain and new wine;His heavens also drop down dew.
