Now Amnon had a friend named Jonadab, the son of David’s brother Shimeah. Jonadab was a very crafty man.

a wise woman called out from the city, “Listen up! Listen up! Tell Joab, ‘Come near so that I may speak to you.’”

So Joab sent to Tekoa and brought from there a wise woman. He told her, “Pretend to be in mourning ¹  and put on garments for mourning. Don’t anoint yourself with oil. Instead, act like a woman who has been mourning for the dead for some time. ² 

Your servant Joab did this so as to change this situation. But my lord has wisdom like that of the angel of God, and knows everything that is happening in the land.” ¹
