11 Perchance we may seem to have fallen aside from the subject; but to say thus much, is no departure from it. For we do not wish to read you histories merely for their own sake, but that you may correct each of the passions which trouble you: therefore also we make these frequent appeals, preparing our discourse for you in all varieties of style; since it is probable that in so large an assembly, there is a great variety of distempers; and our task is to cure not one only, but many different wounds; and therefore it is necessary that the medicine of instruction should be various.
Let us however return there from whence we made this digression: “And the Priest said, Let us draw near unto God. And Saul asked counsel of God. Shall I go down after the strangers? Will You deliver them into my hands? But on that day the Lord answered him not.” Observe the benignity and mildness of God who loves man. For He did not launch a thunderbolt, nor shake the earth; but what friends do to friends, when treated contemptuously, this the Lord did towards the servant. He only received him silently, speaking by His silence, and by it giving utterance to all His wrath.
This Saul understood, and said, as it is recorded, “Bring near hither all the tribes of the people, and know and see in whom this sin has been this day. For as the Lord lives, Who has saved Israel, though the answer be against Jonathan my son, he shall surely die.” Do you see his rashness? Perceiving that his first oath had been transgressed, he does not even then learn self-control, but adds again a second. Consider also the malignity of the devil. For since he was aware that frequently the son when discovered, and publicly arraigned, is able by the very sight at once to make the father relent, and might soften the king's wrath, he anticipated his sentence by the obligation of a second oath; holding him by a kind of double bond, and not permitting him to be the master of his own determination, but forcing him on every side to that iniquitous murder.
And even while the offender was not yet produced, he has passed judgment, and while ignorant of the criminal, he gave sentence. The father became the executioner; and before the enquiry declared his verdict of condemnation! What could be more irrational than this proceeding?
