'Known' in the Bible

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

Be it known now to the king that if this city is built, and the walls finished, they will not pay tribute, custom, or toll, and in the end it will be hurtful 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 built with great stones, and timber is laid in the walls; and this work goes on with diligence and prospers in their hands.
