A body of troops stationed for defense, often in the sense of occupying forces. In the tenth century B.C. the Philistines had garrisons deep in Jewish territory at Gibeath-elohim (1 Samuel 10:5), Geba (1 Samuel 13:3), and Bethlehem (2 Samuel 23:14). David, in turn, placed garrisons in Damascus (2 Samuel 8:6) and in Edom (2 Samuel 8:14) with the result that the natives became his servants, that is, they were subjugated and forced to pay tribute.
The KJV has garrisons at
Ezekiel 26:11 where modern translations have a reference to pillars in honor of the gods of Tyre. The KJV of
2 Corinthians 11:32 mentions that the city of Damascus was guarded with a garrison. Modern versions simply note the city was guarded. The parallel in
Acts 9:24 only mentions guards at the gate.
