"The cause why"

1. Josh. 5: 4
     4 And this is the cause why Joshua did circumcise: All the people that came out of Egypt, that were males, even all the men of war, died in the wilderness by the way, after they came out of Egypt.
2. Alma 22: 3
     3 And now, O king, if thou wilt spare our lives, we will be thy servants. And the king said unto them: Arise, for I will grant unto you your lives, and I will not suffer that ye shall be my servants; but I will insist that ye shall administer unto me; for I have been somewhat troubled in mind because of the generosity and the greatness of the words of thy brother Ammon; and I desire to know the cause why he has not come up out of Middoni with thee.
3. Alma 58: 9
     9 And now the cause of these our embarrassments, or the cause why they did not send more strength unto us, we knew not; therefore we were grieved and also filled with fear, lest by any means the judgments of God should come upon our land, to our overthrow and utter destruction.
