John Wesley
For the LORD taketh pleasure in his people: he will beautify the meek with salvation.
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.
Let the saints be joyful in glory: let them sing aloud upon their beds.
In glory — For the honour which God putteth upon them.
Beds — By night as well as by day.
To execute vengeance upon the heathen, and punishments upon the people;
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.
To execute upon them the judgment written: this honour have all his saints. Praise ye the LORD.
Written — Appointed and declared in the holy scripture.
