Behold, bless ye the Lord, all ye servants of the Lord,.... All men are of right the servants of God being his creatures; and are under obligation, through his providential goodness, to bless and praise him; though they are not all in fact so: but all good men are, being made so by the power of divine grace; which frees them from the servitude of sin, Satan, and the world, and makes them willing to serve the Lord; as they do in righteousness and holiness, with reverence and godly fear, heartily and willingly, and with great pleasure; and yet have no dependence on any service they perform: and as these are under the highest obligations to bless the Lord; the is, to ascribe greatness to him, to give him the glory of his works, and thanks for his mercies, temporal and spiritual; so they do in this way, and for those things, bless and praise him, to which they are here excited;

Beth Habbechirah, c. 7. s. 6. . The priests watched in three places, and the Levites in twenty one, according to the Jewish MisnahF5Middot, c. 1. s. 1. . The Targum is,
"who stand in the watch house of the sanctuary of the Lord, and praise in the nights;'

Under the Gospel dispensation all the saints are priests, and they have a place in the house of the Lord; where they wait upon him in his ordinances, and serve him, and which they do continually. Some understand, by "nights", times of affliction, darkness, and desertion.
