“Then said Abishai to David, God hath delivered thine enemy into thine hand this day: now therefore let me smite him, I pray thee, with the spear even to the earth at once, and I will not smite him the second time.”
King James Version (KJV)
26:6 Zerujah - David's sister. His father is not named either because he was now dead; or because he was an obscure person.
26:7 Came - That is, to Saul's host. It might seem a bold and strange attempt; but it may be considered: That David had a particular assurance that God would preserve him to the kingdom. That he had a special instinct from God, to this work; and possibly God might inform him, that he had cast them into a deep sleep, that he might have this second opportunity of manifesting his innocency towards Saul.
26:9 Destroy him not, &c. - Though Saul be a tyrant, yet he is our Lord and king; and I, though designed king, as yet am his subject; and therefore cannot kill him without sin, nor will I consent that thou shouldst do it.
