Knowing their thoughts. — The better MSS. give “seeing,” as with an immediate act of intuition. St. Mark adds his usual “immediately,” and both he and St. Luke use the word which implies fulness of knowledge.
Wherefore think ye evil? — Literally, evil things. The thoughts were evil because, in face of the mighty works and the divine wisdom of the Teacher, they were assuming that He had wantonly spoken words that involved the most extreme of all forms of sin against the God in whose name He taught.
