Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 23
Then spake Jesus to the multitude, and to his disciples, Saying, The Scribes and the Pharisees sit in Moses’ seat: All therefore whatsoever they bid you observe, that observe and do; but do not ye after their works: for they say, and do not. For they bind heavy burdens and grievous to be borne, and lay them on men’s shoulders; but they themselves will not move them with one of their fingers.
And to the Scribes and Pharisees of whom He is now speaking, heavy burdens not to be borne are the commandments of the Law; as St. Peter speaks in the Acts, Why seek ye to put a yoke upon the neck of the disciples, which neither we nor our fathers were able to bear? (Acts 15:10.) For commending the burdens of the Law by fabulous proofs, they bound as it were the shoulders of the heart of their hearers with bands, that thus tied as though with proof of reason to them, they might not fling them off; but themselves did not in the least measure fulfil them, that is, not only did not wholly, but did not so much as attempt to.
