41. Now therefore arise] This whole verse corresponds (with some variation of reading) with verses 8, 9 of Psalm cxxxii. For the invocation to arise, compare Numbers x. 35, the ancient chant of the Ark.
the ark of thy strength] This appellation of the Ark refers to its use in war; compare 1 Samuel iv. 3, 6, 7.
with salvation] i.e. with victory. In Psalms cxxxii. 9, with righteousness. The thought in Chronicles and in Psalms cxxxii. is the same, for through victory the human victor receives salvation (i.e. deliverance from the enemy), and the Divine Giver of victory asserts His righteousness (i.e. by giving victory to the right).
thy saints] i.e. thy people Israel regarded as faithful worshippers of Jehovah; compare Psalms lxxix. 2, Psalms cxlix. 5. So in the New Testament the Christians as a body are spoken of as “saints” and “sanctified.”
rejoice in goodness] Render (with margin), rejoice in good, i.e. in prosperity. In Psalms cxxxii. 9, shout for joy.
⁴²O Lord God, turn not away the face of thine anointed; remember the mercies[¹] of David thy servant.
[¹] Or, good deeds See chapter xxxii. 32.
42. turn not away] Compare Psalms cxxxii. 10.
remember the mercies of David] i.e. either show David’s son the mercies thou didst show to David himself (Isaiah lv. 3), or (as margin), remember the good deeds, or “mercies” (so also xxxii. 32), which David did, and reward his son.
