Bible Verses About Abishai: Seeks Saul's life

David said to Achimelekh the Hitti and Avishai the son of Tz'ruyah, Yo'av's brother, "Who will go down with me to Sha'ul in the camp?" Avishai said, "I will go down with you."

So David and Avishai went to the soldiers by night. Sha'ul was lying there asleep inside the barricade. His spear was stuck in the ground next to his head, with Avner and the troops asleep all around him.

Avishai said to David, "God has handed your enemy over to you today; so now, please, let me pin him to the ground with just one stroke of the spear. I won't strike him a second time."
