Then the legislator of morality and human conduct stooped down to the ground, smoothed out the dust with the palm of His hand, and began to write (John 8:6). What did the Lord write in the dust? The Evangelist maintains silence concerning this and does not write of it. It was too repulsive and vile to be written in the Book of Joy. However, this has been present in tradition, and it is horrible. The Lord wrote something unexpected and startling for the elders, the accusers of the sinful woman. With His finger He disclosed their secret iniquities. For these pointers-out of the sins of others were experts in concealing their own sins. But it is pointless to try to hide anything from the eyes of One Who sees all.
"M (eshulam) has stolen treasures from the temple," wrote the Lord's finger in the dust.
"A (sher) has committed adultery with his brother's wife;
"S (halum) has committed perjury;
"E (led) has struck his own father;
"A (marich) has committed sodomy;
"J (oel) has worshipped idols."
And so one statement after another was written in the dust by the awesome finger of the righteous Judge. And those to whom these words referred, bending down, read what was written, with inexpressible horror. They trembled from fright, and dared not look one another in the eye. They gave no further thought to the sinful woman. They thought only of themselves and of their own death, which was written in the dust. Not a single tongue was able to move, to pronounce that troublesome and evil question, "What sayest Thou?" The Lord said nothing. That which is so filthy is fit to be written only in filthy dust. Another reason why the Lord wrote on the ground is even greater and more wonderful. That which is written in the dust is easily erased and removed. Christ did not want their sins to be made known to everyone. Had He desired this, He would have announced them before all the people, and would have accused them and had them stoned to death, in accordance with the law. But He, the innocent Lamb of God, did not contemplate revenge or death for those who had prepared for Him a thousand deaths, who desired His death more than everlasting life for themselves. The Lord wanted only to correct them, to make them think of themselves and their own sins. He wanted to remind them that while they carried the burden of their own transgressions, they shouldn't be strict judges of the transgressions of others. This alone did the Lord desire. And when this was done, the dust was again smoothed over, and that which was written disappeared.
