Absalom answered Joab, “I sent for you, saying, ‘Come here, so that I may send you to the king to ask, “Why have I come [back] from Geshur? It would be better for me to still be there.”’ Now then, let me see the king’s face, and if there is guilt in me, let him put me to death.”

Perhaps the Lord will look on the wrong done to me [by Shimei, if he is acting on his own]; and [in that case perhaps] the Lord will this day return good to me in place of his cursing.”

and said to the king, “Let not my lord consider me guilty, nor remember what your servant did wrong on the day my lord the king left Jerusalem, so that the king would take it to heart.

“I was also blameless before Him,And kept myself from wrongdoing.

But David’s heart (conscience) troubled him after he had counted the people. David said to the Lord, “I have sinned greatly in what I have done. But now, O Lord, please take away the sin of Your servant, for I have acted very foolishly.”
