This psalm is by the Septuagint, Vulgate Latin, Syriac, Arabic, and
Ethiopic versions, joined to the former, and makes one psalm with it:
and Kimchi says, that in some books the psalm does not begin here;
but in the best and correct copies of the Hebrew, and in the Targum,
it stands a distinct psalm; and the different subject matter or
argument shows it to be so. It is ascribed to various persons; by
some to Moses and the Israelites, when pursued by Pharaoh: by others
to the three companions of Daniel, cast into the fiery furnace: by
others to Mordecai and Esther, when Haman distressed the Jews: by
others to the heroes at the times of Antiochus and the Maccabees; so
Theodoret: by some to Jehoshaphat, when a numerous army came against
him; and by others to David, which is more probable; though on what
occasion is not easy to say: some have thought it was written by him,
when insulted by the Jebusites, \\#2Sa 5:6\\. The occasion of it
seems to be some distress the church of God was in from the Heathens;
and the design of it is to encourage trust and confidence in the
Lord; and to excite the saints to give him the glory of all their
mercies, and to expose the vanity of idols.
