Albert Barnes Commentary Luke 6:11

"But they were filled with madness; and communed one with another what they might do to Jesus." — Luke 6:11 (ASV)

Were filled with madness. The reasons were probably as follows:

1. Because he had shown his power to work a miracle.
2. Because he had shown his power to do it contrary to what they thought was right.
3. Because by doing it he had shown that he was from God, and that they were therefore wrong in their views of the Sabbath. And,
4. Because he had shown no respect to their views of what the law of God demanded.

Pride, obstinacy, malice, and disappointed self-confidence were all combined, therefore, in producing madness. Nor were they alone. Men are often enraged because others do good in a way which they do not approve of. God gives success to others; and because he has not accommodated himself to their views of what is right, and done it in the way which they would have prescribed, they are enraged, and filled with envy at men more successful than themselves.

Communed one with another means they spoke together, or laid a plan.
