They say unto Him, Master, this woman was taken in adultery, in the very act. Now Moses in the law commanded us, that such should be stoned: but what sayest Thou?Now these very men who took her to Jesus, and all who took part, also have committed adultery.... in their heart, they would probably have enjoyed doing the same, but being in the public eye as righteous men, they knew they would lose their position and power.
The point is, there is nobody without sin, so let's not look upon another's sin, but be concerned our own heart.
JOHN 8:4-5
