Matthew Poole and continuators on 1 Samuel 22:6

6 ¶ When Saul heard that David was discovered, and the men that were with him: (now Saul abode in Gibeah under a tree in Ramah , having his spear in his hand , and all his servants were standing about him).

i. e. In the Territory of Gibeah, in, or near (for so the Hebrew Particle is oft used; as hath been shewed) Ramah. Or, in the town of Gibeah—in an high place; for so the Word Ramah unquestionably signifies; and so it is here rendred by some, both Ancient and Modern Interpreters.

Either as an Ensign of Majesty, for in old times Kings carried a Spear instead of a Scepter; as Iustin and others note; Or, as an Instrument of Self-defence or Cruelty, as occasion required.

Marginal references: Or, grove in a high place.
