And a woman in the city, who was a sinner, having learned that he was eating in the Pharisee's house, brought an alabaster jar of ointment. She stood behind him at his feet, weeping, and began to bathe his feet with her tears and to dry them with her hair. Then she continued kissing his feet and anointing them with the ointment. Now when the Pharisee who had invited him saw it, he said to himself, "If this man were a prophet, he would have known who and what kind of woman this is who is touching him-- that she is a sinner." […] [Then Jesus said to the Pharisee:] "I tell you, her sins, which were many, have been forgiven; hence she has shown great love. But the one to whom little is forgiven, loves little." Then he said to her, "Your sins are forgiven." But those who were at the table with him began to say among themselves, "Who is this who even forgives sins?" (NRSV 7:37-39, 47-49)
And, behold, a woman in the city, which was a sinner, when she knew that Jesus sat at meat in the Pharisee's house, brought an alabaster box of ointment, And stood at his feet behind him weeping, and began to wash his feet with tears, and did wipe them with the hairs of her head, and kissed his feet, and anointed them with the ointment. Now when the Pharisee which had bidden him saw it, he spake within himself, saying, This man, if he were a prophet, would have known who and what manner of woman this that toucheth him: for she is a sinner. […] [Then Jesus said to the Pharisee:] I say unto thee, Her sins, which are many, are forgiven; for she loved much: but to whom little is forgiven, the same loveth little. And he said unto her, Thy sins are forgiven. And they that sat at meat with him began to say within themselves, Who is this that forgiveth sins also? (KJV 7:37-39, 47-49)
The woman's sins aren't specified, but really, how long is the list of potential sins in male-centered antiquity that could earn a woman this kind of reputation? In other words, they probably have to do with illicit sex. At any rate, Jesus is again criticized for forgiving sins (compare 5:21).
