'Falling' in the Bible

And when he was in the gate of Benjamin, a captain of the ward was there, whose name was Irijah, the son of Shelemiah, the son of Hananiah; and he laid hold on Jeremiah the prophet, saying, Thou art falling away to the Chaldeans.

Then said Jeremiah, It is false; I am not falling away to the Chaldeans. But he hearkened not to him; so Irijah laid hold on Jeremiah, and brought him to the princes.
