2-samuel 3:39

I am this day weak - Had Abner lived, all the tribes of Israel would have been brought under my government.

Though anointed king - I have little else than the title: first, having only one tribe under my government; and secondly, the sons of Zeruiah, Joab and his brethren, having usurped all the power, and reduced me to the shadow of royalty.

The Lord shall reward the doer of evil - That is, Joab, whom he appears afraid to name.

We talk much of ancient manners, their simplicity and ingenuousness; and say that the former days were better than these. But who says this who is a judge of the times? In those days of celebrated simplicity, etc., there were not so many crimes as at present I:grant: but what they wanted in number they made up in degree: deceit, cruelty, rapine, murder, and wrong of almost every kind, then flourished. We are refined in our vices; they were gross and barbarous in theirs: they had neither so many ways nor so many means of sinning; but the sum of their moral turpitude was greater than ours. We have a sort of decency and good breeding, which lay a certain restraint on our passions, they were boorish and beastly, and their bad passions were ever in full play. Civilization prevents barbarity and atrocity; mental cultivation induces decency of manners: those primitive times were generally without these. Who that knows them would wish such ages to return?

3:39 Weak - In the infancy of my kingdom, not well settled in it.The metaphor is taken from a young and tender child or plant.These men - Joab and Abishai, the sons of thy sister Zeruiah.Too hard - That is, too powerful. They have so great a command over all the soldiers, and so great favour with the people, that I cannot punish them without apparent hazard to my person and kingdom; especially, now when all the tribes, except Judah, are in a state of opposition against me.But although this might give some colour to the delay of their punishment, yet it was a fault that he did not do it within some reasonable time, both because this indulgence proceeded from a distrust of God's power and faithfulness; as if God could not make good his promise to him, against Joab and all his confederates; and because it was contrary to God's law, which severally requires the punishment of willful murderers.It was therefore carnal wicked policy, yea cruel pity that spared him.If the law had had its course against Joab, it is probable the murder of Ishbosheth, Ammon, and others, had been prevented. So truly was he in these, and some other respects, a bloody man, which may be observed to the glory of the Divine grace, in his forgiveness and conversion.
