C. F. Keil and Franz Delitzsch on 1 Samuel 8:11

1Sa 8:11

“He will take your sons, and set them for himself upon his chariots, and upon his saddle-horses, and they will run before his chariot;” i.e., he will make the sons of the people his retainers at court, his charioteers, riders, and runners. The singular suffix attached to בּמרכּבתּו is not to be altered, as Thenius suggests, into the plural form, according to the lxx, Chald., and Syr., since the word refers, not to war-chariots, but to the king’s state-carriage; and פּרשׁ does not mean a rider, but a saddle-horse, as in 2Sa 1:6; 1Ki 5:6, etc.
