PSALM 149
This Psalm rises up to the proper praise of Israel for themselves, as between themselves and God, in this nearness. The saints here are always chasidim (holy ones), i.e., Israel so accepted and beloved in mercy, the meek and God-honouring ones — the Remnant.
This Psalm is the Hallelu-Jah of Israel in its new song, as in and under this blessing, and the instruments of His, the Lord’s, vengeance, for they are witnesses (though receiving it under mercy, is in Psalm 143) of the Lord’s righteousness. Also we have evidence of the use of the word kha-sidaiv (His saints) to be of the Jewish living saints; so, I believe, everywhere.
