Psalms 149:4 - Matthew Poole's English Annotations on the Holy Bible

Taketh pleasure in his people; he loveth them above all people, and rejoiceth over them to do them good. He will beautify, Heb. adorn or glorify; make them amiable and honourable in the eyes of the world, who now hate and despise them. The meek, or humble, to wit, his people, as he now said, who are oft in Scripture described by that character, because all true Israelites are such, and all Israelites profess and ought to be such. Or, the afflicted, as that word is oft used in Scripture, which hath been observed before; his poor afflicted and oppressed people, to whom the following salvation is most needful and acceptable. With salvation; both temporal, in delivering them from, and setting them above, all their enemies; and afterwards, with everlasting salvation and glory.
