Arise, O Lord, into thy rest,.... Which words, and what follow, were used by Solomon at the dedication of the temple; and with which he concluded his prayer, 2Ch 6:41; and so may be a request to the Lord, that he would take up his residence in the temple built for him, where he would have a firm and stable place of rest; who, from the time of Israel's coming out of Egypt, had not dwelt in a house; but had walked in a tent or tabernacle from place to place, 2Sa 6:6; and that he would take up his abode in his church, the antitype of the temple, and rest in his love there, and cause his people to rest also; see Ps 132:13;thou, and the ark of thy strength; the Targum is,"thou, and the ark in which is thy law.'
'This is sometimes called the strength of the Lord; because by it he showed his great strength in destroying the enemies of his people, the Philistines and others; see Ps 78:61. It was a type of Christ, who is the power of God, and the mighty God; and, as man, made strong by the Lord; and, as Mediator, has all strength in him for his people.
