'Sharp' in the Bible

And constantly, day and night, he remained among the tombs or on the hills, shrieking, and mangling himself with sharp stones.

And he let them do it. And the unclean spirits came out and went into the pigs; and the herd went rushing down a sharp slope into the sea, about two thousand of them; and they came to their death in the sea.

And they took to him little children, so that he might put his hands on them: and the disciples said sharp words to them.

And later he was seen by the eleven themselves while they were taking food; and he said sharp words to them because they had no faith and their hearts were hard, and because they had no belief in those who had seen him after he had come back from the dead.
