'Union' in the Bible

the trumpeters and musicians played in union, praising and giving thanks to the LORD. They praised the LORD loudly and sang, "He is good, and his gracious love is eternal," accompanied by the trumpets, cymbals, and other musical instruments.) As they did this, a cloud filled the Temple, that is, the LORD's Temple,

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.
