“And everyone went to his own house.But Jesus went to the Mount of Olives. Now early in the morning He came again into the temple, and all the people came to Him; and He sat down and taught them. Then the scribes and Pharisees brought to Him a woman caught in adultery. And when they had set her in the midst, they said to Him, “Teacher, this woman was caught in adultery, in the very act. Now Moses, in the law, commanded us that such should be stoned. But what do You say?” This they said, testing Him, that they might have something of which to accuse Him. But Jesus stooped down and wrote on the ground with His finger, as though He did not hear.So when they continued asking Him, He raised Himself up and said to them, “He who is without sin among you, let him throw a stone at her first.” And again He stooped down and wrote on the ground. Then those who heard it, being convicted by their conscience, went out one by one, beginning with the oldest even to the last. And Jesus was left alone, and the woman standing in the midst. When Jesus had raised Himself up and saw no one but the woman, He said to her, “Woman, where are those accusers of yours? Has no one condemned you?”She said, “No one, Lord.”And Jesus said to her, “Neither do I condemn you; go and sin no more.”” (John 7:53–8:11, NKJV)
The notes in the MacArthur Study Bible for this passage are as follows:
This section dealing with the adulteress most likely was not a part of the original contents of John. It has been incorporated into various manuscripts at different places in the gospel (e.g., after vv. 36, 44, 52, or 21:25), while one manuscript places it after Luke 21:38. External manuscript evidence representing a great variety of textual traditions is decidedly against its inclusion, for the earliest and best manuscripts exclude it. Many manuscripts mark the passage to indicate doubt as to its inclusion. Significant early versions exclude it. No Gr. church father comments on the passage until the twelfth century. The vocabulary and style of the section also are different from the rest of the gospel, and the section interrupts the sequence of v. 52 with 8:12ff. Many, however, do think that it has all the earmarks of historical veracity, perhaps being a piece of oral tradition that circulated in parts of the western church, so that a few comments are in order. In spite of all these considerations of the likely unreliability of this section, it is possible to be wrong on the issue, and thus it is good to consider the meaning of this passage and leave it in the text, just as with Mark 16:9–20.
