C. F. Keil and Franz Delitzsch on 1 Chronicles 14:1

1Ch 14:1 David’s palace-building, wives and children, 1Ch 14:1-7; cf. 2Sa 5:11-16. Two victories over the Philistines, 1Ch 14:8-17; cf. 2Sa 5:17-25. - The position in which the narrative of these events stands, between the removal of the ark from Kirjath-jearim and its being brought to Jerusalem, is not to be supposed to indicate that they happened in the interval of three months, curing which the ark was left in the house of Obed-edom. The explanation of it rather is, that the author of our Chronicle, for the reasons given in page 170, desired to represent David’s design to bring the ark into the capital city of his kingdom as his first undertaking after he had won Jerusalem, and was consequently compelled to bring in the events of our chapter at a later period, and for that purpose this interval of three months seemed to offer him the fittest opportunity. The whole contents of our chapter have already been commented upon in 2Sa 5:1, so that we need not here do more than refer to a few subordinate points.
