John Wesley’s NotesPsalms 149

The horn - In scripture commonly denotes strength, victory, glory, and felicity.

The Lord - He rejoiceth over them to do them good. Beautify - Heb. adorn, make them amiable and honourable in the eyes of the world, who now hate and despise them. The meek - All true Israelites are such.

In glory - For the honour which God putteth upon them. Beds - By night as well as by day.

Vengeance - For all their cruelties and injuries towards God's people. This was literally accomplished by David upon the Philistines, Ammonites, Syrians and other neighbouring nations.

Written - Appointed and declared in the holy scripture.
