Nehemiah 6:19

Also they reported his good deeds before me, in trying to influence Nehemiah in his favor, and uttered my words to him, informing the enemy of all the matters undertaken by. Nehemiah, so that Tobiah was able to plan new schemes to hinder the work. And Tobiah, with all this information at his command, sent letters to put me in fear. As Nehemiah and the faithful Jews continued in the task set before them in spite of all attempts of the enemies to discourage them, so all true Christians will work for the Lord consistently, letting neither threats nor enticements keep them from performing the labor entrusted to them.
