理雅各英译（1882）
The third SIX, divided, shows calamity happening to one who is free from insincerity - as in the case of an ox that has been tied up. A passer by finds it (and carries it off), while the people in the neighbourhood have the calamity (of being accused and. apprehended).
'The passer-by gets the ox:' - this proves a calamity to the people of the neighbourhood.
