1 Kings (1 Samuel) Chapter 22
(Sa1 22:1-5) David at Adullam, Many resort to him.
(Sa1 22:6-19) Saul destroys the priests of Nob.
(Sa1 22:20-23) Abiathar escapes to David.
See what weak instruments God sometimes uses, to bring about his own purposes. The Son of David is ready to receive distressed souls, who will be commanded by him. He receives all who come unto Him, however vile and miserable; he changes them into a holy people, and employs them in his service: those who would reign with him must be contented first to suffer with and for him. Observe with what tender concern David provided for his aged parents. The first thing he does is to find them a quiet habitation, whatever became of himself. Let children learn to honour their parents, in every thing consulting their ease and satisfaction. Though highly preferred, and much employed, let them not forget their aged parents. The steps of a good man are ordered by the Lord. And the Lord will preserve his people for their appointed work, however they may be hated and exposed.
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.
David greatly lamented the calamity. It is great trouble to a good man to find himself any way the cause of evil to others. He must have been much pained, when he considered that his falsehood was one cause of this fatal event. David speaks with assurance of his own safety, and promises that Abiathar should have his protection. With the Son of David, all who are his may be sure they shall be in safeguard, Psa 91:1. In the hurry and distraction David was continually in, he found time for communion with God, and found comfort in it.
