This psalm is entitled by the Septuagint, Vulgate Latin, Ethiopic, and
Arabic versions, "hallelujah", of Haggai and Zechariah; and by
Apollinarius, the common hymn of them: and the Syriac inscription is
still more expressive,

``it was said by Haggai and Zechariah, prophets, who came up
with the captivity out of Babylon.''

Theodoret says this title was in some Greek copies in his time; but was
not in the Septuagint, in the Hexapla: nor is it in any other Greek
interpreters, nor in the Hebrew text, nor in the Targum; though some
Jewish commentators, as R. Obadiah, take it to be an exhortation to the
captives in Babylon to praise the Lord: and Kimchi interprets it of
their present captivity and deliverance from it; and observes, that the
psalmist seeing, by the Holy Spirit, the gathering of the captives,
said this with respect to Israel; and so refers it to the times of the
Messiah, as does also Jarchi, especially the \\#Ps 146:10\\; and which,
though they make it to serve an hypothesis of their own, concerning
their vainly expected Messiah; yet it is most true, that the psalm is
concerning the Messiah and his kingdom, to whom all the characters and
descriptions given agree.
