'Regret' in the Bible

And later, David was full of regret for cutting off Saul's skirt.

And when the hand of the angel was stretched out in the direction of Jerusalem, for its destruction, the Lord had regret for the evil, and said to the angel who was sending destruction on the people, It is enough; do no more. And the angel of the Lord was by the grain-floor of Araunah the Jebusite.

And God sent an angel to Jerusalem for its destruction: and when he was about to do so, the Lord saw, and had regret for the evil, and said to the angel of destruction, It is enough; do no more. Now the angel of the Lord was by the grain-floor of Ornan the Jebusite.

I took note and gave ear, but no one said what is right: no man had regret for his evil-doing, saying, What have I done? everyone goes off on his way like a horse rushing to the fight.

Truly, after I had been turned, I had regret for my ways; and after I had got knowledge, I made signs of sorrow: I was put to shame, truly, I was covered with shame, because I had to undergo the shame of my early years.
