15 Was that day the first time I inquired of God for him? Of course not! Let not the king accuse your servant or any of his father's family, for your servant knows nothing at all about this whole affair."
15 Is today the first time that I have inquired of God for him? No! Let not the king impute anything to his servant or to all the house of my father, for your servant has known nothing of all this, much or little."
15 Do you think that was the first time I prayed with him for God's guidance? Hardly! But don't accuse me of any wrongdoing, me or my family. I have no idea what you're trying to get at with this 'outlaw' talk."
15 Did I then begin to inquire of God for him? Far be it from me! Let not the king impute anything to his servant, or to any in the house of my father. For your servant knew nothing of all this, little or much."
15 This was certainly not the first time I had consulted God for him! May the king not accuse me and my family in this matter, for I knew nothing at all of any plot against you."
Matthew Henry's Commentary on 1 Samuel 22:15
Commentary on 1 Samuel 22:6-19
(Read 1 Samuel 22:6-19)
See the nature of jealous malice and its pitiful arts. Saul looks upon all about him as his enemies, because they do not just say as he says. In Ahimelech's answer to Saul we have the language of conscious innocence. But what wickedness will not the evil spirit hurry men to when he gets the dominion! Saul alleges that which was utterly false and unproved. But the most bloody tyrants have found instruments of their cruelty as barbarous as themselves. Doeg, having murdered the priests, went to the city, Nob, and put all to the sword there. Nothing so vile but those may do it, who have provoked God to give them up to their hearts' lusts. Yet this was the accomplishment of the threatenings against the house of Eli. Though Saul was unrighteous in doing this, yet God was righteous in permitting it. No word of God shall fall to the ground.
