Judges 3:19

But he himself turned again from the quarries that were by Gilgal, and said, I have a secret errand unto thee, O king: who said, Keep silence. And all that stood by him went out from him.

Quarries. There are no remains of quarries in that neighborhood. The Hebrew word is х hapªciyliym (H6456)], the pillars, the piles of stone, the carved images (Deuteronomy 7:25; Jeremiah 8:19; Jeremiah 51:52); statues of Moabite idols, the sight of which kindled the patriotic zeal of Ehud to avenge this public insult to Israel on its author. They had probably been set up as landmarks, determining the boundaries of the Hebrew territory from the Moabite acquisition on the west of the Jordan; because boundary stones were commonly, as the Roman Iapides, sacred and inviolate.

I have a secret errand to thee, O King: who said, Keep silence - `privacy:' a signal for all to, withdraw.
