'Known' in the Bible

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

Be it known now unto the king, that, if this city be builded, and the walls finished, they will not pay tribute, custom, or toll, and in the end it will be hurtful unto the kings.

Be it known unto the king, that we went into the province of Judah, to the house of the great God, which is builded with great stones, and timber is laid in the walls; and this work goeth on with diligence and prospereth in their hands.
