And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst.

People's New Testament

8:7-9 He that is without sin among you. When they persisted, saying, What sayest thou ? he said what was an awful rebuke. They knew that he knew their lives, that they were as guilty as the woman they had brought. They forgot the demand of Moses that the witnesses should cast the first stone (De 17:5-7), and his answer was like a bolt of lightning. Covered with shame, when he stooped and wrote again, they went out one by one.

Wesley's Notes

8:9 Beginning at the eldest - Or the elders. Jesus was left alone - By all those scribes and Pharisees who proposed the question. But many others remained, to whom our Lord directed his discourse presently after.

Jamieson-Fausset-Brown Bible Commentary

9. they . convicted . went out one by one . Jesus was left alone-that is, without one of her accusers remaining; for it is added.

the woman in the midst-that is, of the remaining audience. While the trap failed to catch Him for whom it was laid, it caught those who laid it. Stunned by the unexpected home thrust, they immediately made off-which makes the impudence of those impure hypocrites in dragging such a case before the public eye the more disgusting.

Matthew Henry's Concise Commentary

8:1-11 Christ neither found fault with the law, nor excused the prisoner's guilt; nor did he countenance the pretended zeal of the Pharisees. Those are self-condemned who judge others, and yet do the same thing. All who are any way called to blame the faults of others, are especially concerned to look to themselves, and keep themselves pure. In this matter Christ attended to the great work about which he came into the world, that was, to bring sinners to repentance; not to destroy, but to save. He aimed to bring, not only the accused to repentance, by showing her his mercy, but the prosecutors also, by showing them their sins; they thought to insnare him, he sought to convince and convert them. He declined to meddle with the magistrate's office. Many crimes merit far more severe punishment than they meet with; but we should not leave our own work, to take that upon ourselves to which we are not called. When Christ sent her away, it was with this caution, Go, and sin no more. Those who help to save the life of a criminal, should help to save the soul with the same caution. Those are truly happy, whom Christ does not condemn. Christ's favour to us in the forgiveness of past sins should prevail with us, Go then, and sin no more.
