As he came forth of his mother's womb, naked shall he return to go as he came, and shall take nothing of his labour, which he may carry away in his hand.

That which hath been is named already, and it is known that it is man: neither may he contend with him that is mightier than he.

Where the word of a king is, there is power: and who may say unto him, What doest thou?
