Atos 13:25

25 As John was completing his work, he said: 'Who do you suppose I am? I am not the one you are looking for. But there is one coming after me whose sandals I am not worthy to untie.'

25 And as John was fulfilling his course, he said, What suppose ye that I am? I am not [he]. But behold, there cometh one after me the shoes of whose feet I am not worthy to unloose.
