'Wherefore' in the Bible

Wherefore the king said unto me, Why is thy countenance sad, seeing thou art not sick? this is nothing else but sorrow of heart. Then I was very sore afraid,

and say to the king, 'Let the king to the age live! wherefore should not my face be sad, when the city, the place of the graves of my fathers, is a waste, and its gates have been consumed with fire?'

And I strive with the prefects, and say, 'Wherefore hath the house of God been forsaken?' and I gather them, and set them on their station;

and I testify against them, and say unto them, 'Wherefore are ye lodging over-against the wall? if ye repeat it, a hand I put forth upon you;' from that time they have not come in on the sabbath.
