Barnes New Testament Notes

Verse 2. Transgress the tradition of the elders, The word elders means, literally, old men. It here means the ancients, or their ancestors. Tradition means something handed down from one to another by memory: some precept or custom not commanded in the written law, but which they held themselves bound to observe. The Jews supposed that when Moses was on Mount Sinai, two sets of laws were delivered to him: one, they said, was recorded, and is that contained in the Old Testament; the other was handed down from father to son, and kept uncorrupted to their day. They believed that Moses before he died delivered this law to Joshua; he to the judges; they to the prophets; so that it was kept pure till it was recorded in the Talmuds. In these books these pretended laws are now contained. They are exceedingly numerous, and very trifling. They are, however, regarded by the Jews as more important than either Moses or the prophets. One point in which the Pharisees differed from the Sadducees was in holding to these traditions. It seems, however, that in the particular traditions here mentioned all the Jews combined.

The Pharisees, and all the Jews, except they wash their hands oft, eat not, Mr 7:3. Mark has also added, that this custom of washing extended not merely to their hands before eating, but in coming from the market; and also to pots, and cups, and brazen vessels and tables, Mr 7:3,4. They did this professedly for the sake of cleanliness. So far it was well. But they made it a matter of superstition. They regarded external purity as of much more importance than the purity of the heart. They had many foolish rules about it: as, the quantity of water that was to be used; the way in which it should be applied; the number of times it should be changed; the number of those that might wash at a time, etc. These foolish rules our Saviour did not think it proper to regard; and this was the reason why they found fault with him.
