Nehemiah 6:10

Afterward I came unto the house of Shemaiah the son of Delaiah the son of Mehetabeel, who was shut up; and he said, Let us meet together in the house of God, within the temple, and let us shut the doors of the temple: for they will come to slay thee; yea, in the night will they come to slay thee.

Afterward I came into the house of Shemaiah ... This man was the son of a priest, who was an intimate and confidential friend of Nehemiah. The young man claimed to been endowed with the gift of prophecy. Having been secretly bribed by Sanballat, he, in his pretended capacity of prophet, told Nehemiah that his enemies were that night to make an attempt upon his life; and advised him, at the same time, to consult his safety by concealing himself in the sanctuary-a crypt which, from its sanctity, was strong and secure. But the noble-minded governor determined at all hazards to remain at his post, and not bring discredit on the cause of God and religion by his unworthy cowardice in leaving the temple and city unprotected.
