Adam Clarke on 1 Samuel 22:6

Saul abode in Gibeah - Saul and his men were in pursuit of David, and had here, as is the general custom in the East, encamped on a height, for so Ramah should be translated, as in the margin. His spear, the ensign of power (see on 1Sam 18:11 (note)), was at hand, that is stuck in the ground where he rested, which was the mark to the soldiers that there was their general's tent.

And all his servants were standing about him - That is, they were encamped around him, or perhaps here there is a reference to a sort of council of war called by Saul for the purpose of delivering the speech recorded in the following verses.
