Barnes' Notes
When Simon Peter saw it - Saw the great amount of fishes; the remarkable success of letting down the net.
He fell down at Jesus' knees - This was a common posture of "supplication." He had no doubt now of the power and knowledge of Jesus. In amazement, wonder, and gratitude, and not doubting that he was in the presence of some divine being, he prostrated himself to the earth, trembling and afraid. So should sinful people "always" throw themselves at the feet of Jesus at the proofs of his power; so should they humble themselves before him at the manifestations of his goodness.
Depart from me - This is an expression of Peter' s humility, and of his consciousness of his unworthiness. It was not from want of love to Jesus; it did not show that he would not be pleased with his favor and presence; but it was the result of being convinced that Jesus was a messenger from God - a high and holy being; and he felt that he was unworthy to be in his presence. In his deep consciousness of sin, therefore, he requested that Jesus would depart from him and his little vessel. Peter' s feeling was not unnatural, though it was not proper to request Jesus to leave him. It was an involuntary, sudden request, and arose from ignorance of the character of Jesus. We "are" not worthy to be with him, to be reckoned among his friends, or to dwell in heaven with him; but he came to seek the lost and to save the impure. He graciously condescends to dwell with those who are humble and contrite, though they are conscious that they are not worthy of his presence; and we may therefore come boldly to him, and ask him to receive us to his home - to an eternal dwelling with him in the heavens.
