'Commissions' in the Bible

Who stirs up this one from the east? Who officially commissions him for service? He hands nations over to him, and enables him to subdue kings. He makes them like dust with his sword, like windblown straw with his bow.

who commissions Cyrus, the one I appointed as shepherd to carry out all my wishes and to decree concerning Jerusalem, 'She will be rebuilt,' and concerning the temple, 'It will be reconstructed.'"
