'Known' in the Bible

Let it be known to the king that the Jews who came up from you have come to us at Jerusalem. They are rebuilding this rebellious and evil city and are finishing its walls and repairing the foundations.

Now let it be known to the king, that if that city is rebuilt and the walls are finished, then they will not pay tax, custom, or toll, and the revenue of the kings will be diminished.

Let it be known to the king that we have gone to the province of Judah, to the house of the great God. It is being built with huge stones, with beams laid in the walls; and this work goes on with diligence and care and is succeeding in their hands.
