With this psalm begins the great "Hallel", which ends with Psalm 118;
and was used to be sung at the Jewish festivals, particularly at the
feast of tabernacles and of the passover; and is thought by some to be
the hymn sung by Christ and his apostles, after the celebration of the
Lord's supper; in which there are many things pertinent to that
occasion as well as to the above feasts. This psalm is a song of praise
for redemption by Christ, to be sung in Gospel times, when the name of
the Lord should be known among all nations, from the rising to the
setting sun. It is thought by some to be an abridgment of the song of
Hannah, \\#1Sa 2:1-10\\, there is an agreement.
