'Union' in the Bible

So I became shepherd of the flock marked for slaughter, paying attention to the oppressed of the flock. I took two staffs naming one "Pleasant" and the other one "Union" - and then I pastured the flock.

So I took the 30 shekels of silver and threw them into the treasury of the Temple of the LORD. Then I broke my second staff the one I had named "Union" - breaking the union between the house of Judah and the house of Israel.
