INTRODUCTION TO PSALM 126 A Song of degrees. This psalm is generally thought to have been written by Ezra, or some good man returned from the Babylonish captivity, and on account of it: the inscription in the Syriac version of it, besides observing it to be a song of degrees or ascents, and without a name, is, "it is said of Haggai and Zechariah, who came up out of Babylon with the captives; but spiritually; and it is an expectation of good things to come.'' It may have respect to redemption by the Messiah; and the conversion of the Jews in the latter day.
