Where does the phrase God speed come from?
“The term God speed, used by some translations of the Holy Scriptures, is a contraction of the saying, “I wish that God may speed you,” or in today’s terminology, “I wish that God may bless you with success.” Both specific uses of “God speed” found in the King James Version have nothing to do with physical motion.” http://www.keyway.ca/htm2003/20031230.htm
