SEV Biblia, Chapter 12:26
¶ Y Joab peleaba contra Rabá de los hijos de Amón, y tomó la ciudad real.
Clarke's Bible Commentary - 2 Samuel 12:26
Verse 26. And took the royal city.] How can this be, when Joab sent to David to come to take the city, in consequence of which David did come and take that city? The explanation seems to be this: Rabbah was composed of a city and citadel; the former, in which was the king's residence, Joab had taken, and supposed he could soon render himself master of the latter, and therefore sends to David to come and take it, lest, he taking the whole, the city should be called after his name.
John Gill's Bible Commentary
Ver. 26. And Joab fought against Rabbah of the children of Ammon , etc.] Of his being sent against it, and of his besieging it, we read in ( 2 Samuel 11:1); but it can hardly be thought that he had been so long besieging it, as that David had two children by Bathsheba; but the account of the finishing of it is placed here, that the story concerning Bathsheba might lie together without any interruption: and took the royal city ; or that part of it in which the king’s palace was, and which, as Abarbinel observes, was without the city, as the palaces of kings now usually are.
Matthew Henry Commentary
Verses 26-31 - To be thus severe in putting the children of Ammon to slavery was sign that David's heart was not yet made soft by repentance, at the time when this took place. We shall be most compassionate, kind, an forgiving to others, when we most feel our need of the Lord's forgivin love, and taste the sweetness of it in our own souls __________________________________________________________________
