Theodoret of Cyrus
Why did the Prophet experience fear when instructed to anoint David? (1 Sam. 16:2) This was due to the fact that he was not just a prophet but also a human being. If our Lord Jesus Christ, the Master of the Prophet, displayed human trepidation while preparing to endure redemptive suffering, who among us can claim to be free of weaknesses and criticize the Prophet for his fear?
Some individuals even go so far as to criticize God, suggesting that He taught the Prophet something false; for He commanded, "Take the young of the oxen in thy hand, and say, I go to eat the Lord"? (1 Sam. 16:2) Yet this is not a deception; the Prophet truly conducted the sacrifice. (1 Sam. 16:2) In fact, the Prophet did indeed fulfill the sacrificial act.
