This they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with his finger wrote on the ground, as though he heard them not.

People's New Testament

8:6 Jesus stooped down, and... wrote. As though to say he understood their purposes and would pay no attention to them. This is the only time in the New Testament that our Lord is described as writing.

Wesley's Notes

8:6 That they might have to accuse him - Either of usurping the office of a judge, if he condemned her, or of being an enemy to the law, if he acquitted her. Jesus stooping down, wrote with his finger on the ground - God wrote once in the Old Testament; Christ once in the New: perhaps the words which he afterward spoke, when they continued asking him. By this silent action, he, fixed their wandering, hurrying thoughts, in order to awaken their consciences: and, signified that he was not then come to condemn but to save the world.

Jamieson-Fausset-Brown Bible Commentary

6. stooped down-It will be observed He was sitting when they came to Him.

with his finger wrote on the ground-The words of our translators in italics ("as though He heard them not") have hardly improved the sense, for it is scarcely probable He could wish that to be thought. Rather He wished to show them His aversion to enter on the subject. But as this did not suit them, they "continue asking Him," pressing for an answer. At last, raising Himself He said.

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.
