'Midst' in the Bible

But false prophets arose among the people, just as there will be false teachers among you. These false teachers will infiltrate your midst with destructive heresies, even to the point of denying the Master who bought them. As a result, they will bring swift destruction on themselves.

(For their lawless deeds were torture, day after day, to the pure soul of that righteous man--all that he saw and heard whilst living in their midst.)
