Nehemiah 5:16

Yea, also I continued in the work Overseeing, directing, and encouraging the workmen, which was my whole business; and this at my own cost. Neither bought we any land Of our poor brethren, whose necessities gave abundant opportunities of enriching myself by good bargains. And all my servants were gathered unto the work They also were constantly employed in the same work, and received no pay for their labour, though they could not be so employed without the neglect of my own private business.
