24:1-9 For the people's sin David was left to act wrong, and in his chastisement they received punishment. This example throws light upon God's government of the world, and furnishes a useful lesson. The pride of David's heart, was his sin in numbering of the people. He thought thereby to appear the more formidable, trusting in an arm of flesh more than he should have done, and though he had written so much of trusting in God only. God judges not of sin as we do. What appears to us harmless, or, at least, but a small offence, may be a great sin in the eye of God, who discerns the thoughts and intents of the heart. Even ungodly men can discern evil tempers and wrong conduct in believers, of which they themselves often remain unconscious. But God seldom allows those whom he loves the pleasures they sinfully covet.

9. Joab gave up the sum of the number of the people unto the king—The amount here stated, compared with 1Ch 21:5, gives a difference of three hundred thousand. The discrepancy is only apparent, and admits of an easy reconciliation; thus (see 1Ch 27:1-15), there were twelve divisions of generals, who commanded monthly, and whose duty was to keep guard on the royal person, each having a body of troops consisting of twenty-four thousand men, which, together, formed an army of two hundred eighty-eight thousand; and as a separate detachment of twelve thousand was attendant on the twelve princes of the twelve tribes mentioned in the same chapter, so both are equal to three hundred thousand. These were not reckoned in this book, because they were in the actual service of the king as a regular militia. But 1Ch 21:5 joins them to the rest, saying, "all those of Israel were one million, one hundred thousand"; whereas the author of Samuel, who reckons only the eight hundred thousand, does not say, "all those of Israel," but barely "and Israel were," &c. It must also be observed that, exclusive of the troops before mentioned, there was an army of observation on the frontiers of the Philistines' country, composed of thirty thousand men, as appears from 2Sa 6:1; which, it seems, were included in the number of five hundred thousand of the people of Judah by the author of Samuel. But the author of Chronicles, who mentions only four hundred seventy thousand, gives the number of that tribe exclusive of those thirty thousand men, because they were not all of the tribe of Judah, and therefore he does not say, "all those of Judah," as he had said, "all those of Israel," but only, "and those of Judah." Thus both accounts may be reconciled [Davidson].
