'Drop' in the Bible

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

At Thebez, who struck Abimelech son of Jerubbesheth? Didn’t a woman drop an upper millstone on him from the top of the wall so that he died? Why did you get so close to the wall?’—then say, ‘Your servant Uriah the Hittite is dead also.’”

Look, the nations are like a drop in a bucket;they are considered as a speck of dust in the scales;He lifts up the islands like fine dust.

Then I will knock your bow from your left hand and make your arrows drop from your right hand.
