SEV Biblia, Chapter 20:20
Y Joab respondió, diciendo: Nunca tal, nunca tal me acontezca, que yo destruya ni deshaga.
John Gill's Bible Commentary
Ver. 20. And Joab answered and said, far be it from me, far be it from me , etc.] He repeats these words, to show how detestable it was to him to do what she suggested: that I should swallow up or destroy ; any in a violent and unrighteous manner, and especially a city of which she had given such a character for its greatness and worth, and for the peaceableness and fidelity of its inhabitants.
Matthew Henry Commentary
Verses 14-22 - Justly is that place attacked, which dares to harbour a traitor; no will the heart fare better which indulges rebellious lusts, that wil not have Christ to reign over them. A discreet woman, by her pruden management, satisfied Joab, and yet saved the city. Wisdom is no confined to rank or sex; it consists not in deep knowledge; but in understanding how to act as matters arise, that troubles may be turne away and benefits secured. A great deal of mischief would be prevented if contending parties would understand one another. Let both sides be undeceived. The single condition of peace is, the surrender of the traitor. It is so in God's dealing with the soul, when besieged by conviction and distress; sin is the traitor; the beloved lust is the rebel: part with that, cast away the transgression, and all shall be well. There is no peace on any other terms.
