John Lightfoot on John 9:6

[He spat on the ground, &c.] I. How far spittle was accounted wholesome for weak eyes, we may learn from this ridiculous tale:

"R. Meir sat, and was teaching in the evening of the sabbath day. There was a woman stood by hearing him preach; after he had done she went home and found her candle gone out. Her husband saith to her, 'Where hast thou been?' 'I have been,' saith she, 'standing and hearing the voice of a preacher.' Her husband saith to her, 'Thou shalt not enter in till thou hast gone and spat in the face of him that taught.' After three weeks, her neighbouring women persuading and heartening her to it, she goes to the chapel. Now the whole matter was already made known to R. Meir. He saith therefore to them, 'Is there ever a woman among you skilled in muttering charms over eyes?' [for he feigned a grievous ailment in his eyes:] The woman said, 'R., I am skilled': 'However,' saith he, 'do you spit seven times upon my eyes, and I shall be healed'; which she did." Gloss: "Whenever they muttered any charms over the eyes, it was necessary that they should spit upon them."

II. It was prohibited amongst them to besmear the eyes with spittle upon the sabbath day upon any medicinal account, although it was esteemed so very wholesome for them.

"They do not squirt wine into the eyes on the sabbath day, but they may wash the eyebrows with it: but as to fasting spittle" [which was esteemed exceedingly wholesome], "it is not lawful to put it so much as upon the eyelids." "One saith, that wine is prohibited so far that it may not be injected into the middle of the eyes; upon the eyebrows it may. Another saith that spittle is forbidden so much as upon the eyelids."

So that in this action of our Saviour's we may observe,

I. That he does not heal this sick man with a word, as he did others; but chooseth to do a thing which was against their canonical observation of the sabbath; designing thereby to make a trial of the man, whether he was so superstitious, that he would not admit such things to be done upon him on the sabbath day. He made an experiment not much unlike this upon the man at Bethesda, as we have before observed.

II. Whiles he mingles spittle with dust, and of that makes a clay to anoint the eyes of the blind man, he thereby avoideth the suspicion of using any kind of charm, and gives rather a demonstration of his own divine power, when he heals by a method contrary to nature; for clay laid upon the eyes, we might believe, should rather put out the eyes of one that sees, than restore sight to one that had been blind. Yea and further, he gave demonstration of the divine authority he himself had over the sabbath, when he heals upon that day by the use of means which had been peculiarly prohibited to be used in it.

The connexion of this chapter with the former is such, that the stories in both seem to have been acted on one and the same day. [Going through the midst of them, and so passed by. And as he passed by, he saw a man which was blind.] If it be so, (which I will not much contend about,) then do they bring the adulterous woman before Christ, yea, and attempt to stone him too, on the sabbath day. Jesus hid himself; or perhaps the sense is, he was hidden; that is, by the multitude that had a favour for him, and compassed him about, lest his enemies should have wreaked their malice and displeasure against him.
