This phrase is an adaptation of Jesus' commandment in the Sermon of Mount (Matthew Ch 5 v 41): "And whosoever shall compel thee to go a mile, go with him twain." A Roman soldier passing by a Jew could order him to carry his pack for one mile under the Roman Impression Law. Instead of one, Jesus asked his followers to go two miles.
