'Known' in the Bible

Be it known to the king that the Jews who came up from thee unto us have come to Jerusalem; they are building the rebellious and the bad city, and they complete the walls and join up the foundations.

Be it known therefore unto the king, that, if this city be built and the walls be completed, they will not pay tribute, tax, and toll, and in the end it will bring damage to the kings.

Be it known to the king that we went into the province of Judah, to the house of the great God, which is being built with great stones, and timber is laid in the walls, and this work is being carried on with diligence, and prospers in their hand.
