Arise, O LORD, into thy rest; thou, and the ark of thy strength. Arise, O Lord, into thy rest; thou and the ark of thy strength - Using the same expressions which Solomon used when he dedicated the temple, 2 Chronicles 6:41, 2 Chronicles 6:42. There are several difficulties in these passages. Ephratah may mean the tribe of Ephraim; and then we may understand the place thus: "I have learned that the ark had been in the tribe of Ephraim, and I have seen it at Kirjath-jearim, or Field of the woods, but this is not a proper place for it, for the Lord hath chosen Jerusalem." It is true that the ark did remain in that tribe from the days of Joshua to Samuel, during three hundred and twenty-eight years; and thence it was brought to Kirjath-jearim, where it continued seventy years, till the commencement of the reign of David over all Israel.
But if we take Psalms 132:6-8, not as the continuation of David's vow, but as the words of the captives in Babylon, the explanation will be more plain and easy: "We have heard, O Lord, from our fathers, that thy tabernacle was formerly a long time at Shiloh, in the tribe of Ephraim. And our history informs us that it has been also at Kirjath-jearim, the fields of the wood; and afterwards it was brought to Jerusalem, and there established: but Jerusalem is now ruined, the temple destroyed, and thy people in captivity. Arise, O Lord, and reestablish thy dwelling-place in thy holy city!" See Calmet and others on this place.
