And let the counsel of thine own heart stand: for there is no man more faithful unto thee than it. For a man’s mind is sometime wont to tell him more than seven watchmen, that sit above in an high tower.
The Bible (14th C BC - 2nd C AD) Christian sacred scripture
Ecclesiasticus (Sirach) 37:13-15 [KJV]
Alt trans.: "Trust also your own judgment, for it is your most reliable counselor. A man's mind has sometimes a way of telling him more than seven watchmen posted on a high tower."
