'Stone' in the Bible

Moreover, if he be gone into a city, then shall all Israel bring ropes to that city, and we will draw it into the river, until there isn't one small stone found there."

When they were at the great stone which is in Gibeon, Amasa came to meet them. Joab was clothed in his apparel of war that he had put on, and on it was a sash with a sword fastened on his waist in its sheath; and as he went forth it fell out.
