Matthew 5:41. Whosoever shall compel thee to go a mile, go with him twain.
There is reference here to an ancient Persian custom, which was adopted by the Persian government. The Persians introduced the use of regular couriers to carry letters or news. See note on Job 9:25 (#407). The king’s courier had absolute command of all help that was necessary in the performance of his task. He could press horses into his service, and compel the owners to company him if he desired. To refuse compliance with his demands was an unpardonable offense against the king.
