Joab said unto the king - This very bad man saw that the measure now recommended by the king was a wrong one, and might be ruinous to the people, and therefore he remonstrates against it in a very sensible speech; but the king was infatuated, and would hear no reason.

And Joab said unto the king,.... Not so rudely and insolently as he did on account of his mourning for Absalom, but in a more modest, decent, and polite manner:

now the Lord thy God add unto the people (how many soever they be) an hundredfold; he wished his subjects were an hundred times more numerous than they were:

and that the eyes of my lord the king may see it; that he might live to see with his own eyes so great an increase:

but why doth my lord the king delight in this thing? he being now old, and therefore it might seem strange to indulge such curiosity, pride, and vanity, and besides quite needless and useless: the numbering of them would not make them more or less; and they were all the king's servants, who were ready to obey him whenever he needed them, whether numbered or not; and it might be prejudicial to them, and bring down the wrath of God upon them, as well as be a troublesome and expensive business; all which, though not expressed here, is hinted at in 1 Chronicles 21:3.

Joab discountenanced the thing: "Jehovah thy God add to the nation, as it is, a hundredfold as many, and may the eyes of my lord the king see it. But why doth my lord the king delight in this thing?" The ו before יוסף stands at the commencement, when what is said contains a sequel to something that has gone before (vid., Ges. 255, 1, a.). The thought to which Joab's words are appended as a sequel, is implied in what David said, "that I may know the number of the people;" and if expressed fully, his words would read somewhat as follows: "If thou hast delight in the greatness of the number of the people, may Jehovah," etc. Joab evidently saw through the king's intention, and perceived that the numbering of the people could not be of any essential advantage to David's government, and might produce dissatisfaction among the people, and therefore endeavoured to dissuade the king from his purpose. וכהם כּהם, "as they (the Israelites) just are," i.e., in this connection, "just as many as there are of them." From a grammatical point of view, כּהם is to be taken as the object to יוסף, as in the parallel passages, Deuteronomy 1:11; 2 Samuel 12:8. Not only did he desire that God would multiply the nation a hundredfold, but that He would do it during the lifetime of David, so that his eyes might be delighted with the immense numbers.

And Joab said unto the king, Now the LORD thy God add unto the people, how many soever they be, an hundredfold, and that the eyes of my lord the king may see it: but why doth my lord the king delight in this thing?

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.
