John Lightfoot on Matthew 12:25

[But Jesus knowing their thoughts.] Behold, O Pharisee, a sign of the true Messias, for a sign you would have: he smells out a wicked man.

"It is written of Messias, The Spirit of the Lord shall rest upon him, and shall make him smell in the fear of the Lord. Rabba said, he shall smell and judge; as it is said, he shall not judge by the sight of his eyes, &c. Ben Cozba reigned two years and a half, and said to the Rabbins, I am the Messias: they said to him, It is written of Messias that he shall smell and judge (the Gloss is, he shall smell out the man, and shall judge and know whether he be guilty). Let us see whether thou canst smell and judge. And when they saw that he could not smell and judge, they slew him."
