'Pebble' in the Bible

[Even] if he withdraws to a city, all Israel will bring up ropes to that city, and they will drag him away to the valley until there [is] not even a pebble to be found."

"Yes, look, I [am] going to command and I will shake the house of Israel among all the nations like one who shakes with a sieve, but not a pebble will fall [to the] ground.
