Daniel 10:20-21

Thomson(i) 20 Then he said, that thou knewest that for which I came to thee, then would I return to fight for the chief of the Persians, for as I was coming, the chief of the Grecians came. 21 But I will tell thee that only which is ordered in a writing of truth. There is indeed none with me solicitous about him, but only Michael your chief.
