Garrisons - The word is used for officers in 1 Kings 4:5, 1 Kings 4:19, and some think that that is its meaning here. Perhaps, however, it is best to take it with the King James Version in the same sense as in 1 Samuel 10:5; 1 Samuel 13:3.
Brought gifts - Rather, “tribute” (and in 2 Samuel 8:2); meaning they became subject and tributary.
