Kings of armies did flee apace - Margin, as in Hebrew, did flee, did flee. This is the Hebrew mode of expressing that which is emphatic or superlative. It is by simply repeating the word. The idea is, that they fled speedily; they fled at once, and in alarm. Psalms 68:12-13 are marked by DeWette as a quotation, and the language is supposed by him to be the substance of the song that was sung by the women as referred to in Psalms 68:11. This supposition is not improbable. The reference is, undoubtedly, to the former victories achieved by the people of God when they went out to war; and the idea is, that when the command came, when God gave the word Psalms 68:11, their foes fled in consternation.
And she that tarried at home divided the spoil - The women remaining in their homes, while the men went out to war. On them devolved the office of dividing the plunder, and of giving the proper portions to each of the victors. They would take an interest in the battle, and receive the booty, and assign the portion due to each of the brave soldiers - the more acceptable as given to them by female hands. Possibly, however, the meaning may be, that the victors would bring the plunder home, and lay it at the feet of their wives and daughters to be divided among the women themselves. The dividing of the spoils of battle after a victory was always an important act. Compare Judges 5:30; Jos 7:21; 1 Chronicles 26:27; Hebrews 7:4.
