"And when the children of thy people shall speak unto thee, saying, Wilt thou not shew us what thou meanest by these? Say unto them, Thus saith the Lord GOD; Behold, I will take the stick of Joseph, which is in the hand of Ephraim, and the tribes of Israel his fellows, and will put them with him, even with the stick of Judah, and make them one stick, and they shall be one in mine hand." — Ezekiel 37:18, 19 KJV.
ANSWER: The Jews became divided after Solomon's death, ten northern tribes forming a new kingdom and two tribes remaining loyal to the dynasty of David. The prophet, by fastening two sticks together symbolically united them. It has no reference to any union in modern times.
