The title of this psalm in the Arabic version is "hallelujah", as in
some preceding ones; it is part of the great "Hallel" sung at the
passover, and with great propriety; since the subject matter of it is
the departure of the children of Israel out of Egypt, typical of our
spiritual redemption by Christ; and of the effectual calling of
God's elect out of a state of nature into a state of grace; and
particularly of the conversion of the Gentiles, and the bringing of
them from Paganism to Christianity: the inscription of the Syriac
version is,

``a psalm without a name, out of the ancient writing;
concerning Moses, who sung praise at the sea; but unto us
the calling of the Gospel, by which we become a new people;
spiritual to God, who is incarnate; to Jesus Christ, who
redeemed us by his blood from the curse of the Scripture (the
law), and hath cleansed us from sin by his Spirit.''
