To the chief Musician, A Psalm for the sons of Korah. This psalm is generally thought to have been composed after the return of the Jews from their captivity in Babylon; and yet when they were in some distress from their neighbours, either in the times of Ezra and Nehemiah, or in the times of Antiochus; but then this deliverance from captivity must be considered as typical of redemption by Christ; for as the title of the Syriac version is, "it is a prophecy concerning Christ;" it speaks of his dwelling in the land, of his salvation being near, and of the glory of the divine perfections as displayed in it; and perhaps some parts of it may respect the conversion of the Jews in the latter day; and Aben Ezra and Kimchi say, it is concerning the captivity of Babylon, yet also of their present captivity.
