1 Samuel 26:6,7

Ahimelech the Hittite A valiant man of that nation, who was a proselyte to the Jewish religion; and not only followed David, but was always near to his person. Abishai Brother to Joab, the son of Zeruiah, David's sister. His father is not named, either because he was now dead, or because he was an obscure person. Abishai said, I will go Either Ahimelech declined it, as too hazardous an enterprise; or Abishai, being a forward young man, offered himself while the other stood deliberating. David and Abishai came to the people by night A bold attempt for two men to come into the midst of an army of three thousand chosen men. But it should be considered, 1st, That David had a particular assurance that God would preserve him to the kingdom; and, 2d, That he probably had a particular impression from God, exciting him to this work, and, possibly, God might reveal to him that he had cast them into this deep sleep, in order that David might have this second opportunity of manifesting his innocence toward Saul.
