And they watched him
The ruler of the synagogue, and the principal men in it; particularly the Scribes and Pharisees, who followed him wherever he went; they observed him diligently, and kept their eyes upon him; this lame man being in the synagogue, to see
whether he would heal him on the sabbath day;
which, knowing his readiness to do good, they might expect he would:
that they might accuse him;
as they had accused his disciples before, of the violation of the sabbath: according to the Evangelist Matthew, they put a question to him, whether it was lawful to heal on the sabbath day? with this view, that they might, one way or another, have something to accuse him of, either to the people, or to the sanhedrim; (See Gill on Matthew 12:10).
