Acts 7:54

When they heard these things
How that Abraham, the father of them, was called before he was circumcised, or the law was given to Moses, or the temple was built, which they were so bigoted to, and charged with speaking blasphemously of; and how that Joseph and Moses were very ill treated by the Jewish fathers, which seemed to resemble the usage Christ and his apostles met with from them; and how their ancestors behaved in the wilderness when they had received the law, and what idolatry they fell into there, and in after times; and how that though there was a temple built by Solomon, yet the Lord was not confined to it, nor would he dwell in it always; and especially when they heard him calling them a stiffnecked people, and uncircumcised in heart and ears; saying, that they persecuted and slew the prophets, and were the betrayers and murderers of an innocent person; and notwithstanding all their zeal for the law, and even though it was ministered to them by angels, yet they did not observe it themselves:

they were cut to the heart;
as if they had been sawn asunder; they were filled with anguish, with great pain and uneasiness; they were full of wrath and madness, and could neither bear themselves nor him:

and they gnashed on him with their teeth:
being enraged at him, and full of fury and indignation against him.
