“And the men of the city said unto him on the seventh day before the sun went down, What is sweeter than honey? and what is stronger than a lion? And he said unto them, If ye had not plowed with my heifer, ye had not found out my riddle.”
King James Version (KJV)
14:18 If ye had not &c. - If you had not employed my wife to find it out, as men plough up the ground with an heifer, thereby discovering its hidden parts; he calls her heifer, because she was joined with him in the same yoke.
