Albert Barnes Commentary Nehemiah 6:2

"that Sanballat and Geshem sent unto me, saying, Come, let us meet together in [one of] the villages in the plain of Ono. But they thought to do me mischief." — Nehemiah 6:2 (ASV)

The choice made of Ono, on the outskirts of Benjamin, 25 or 30 miles from Jerusalem, as the meeting-place, was, no doubt, in order to draw Nehemiah to a distance from his supporters, so that an attack might be made on him with a better chance of success.
