For God did not place the coming inhabited world [Note: "The coming inhabited world" here probably refers to the present Christian age. It was viewed as "coming" from the perspective of Old Testament times], under the control of angels [and] that is the world we are talking about.

For then He would have had to suffer often since the creation of the world; but now at the end of the ages [i.e., the final period of world history] He has been revealed once [for all] to remove sin by sacrificing Himself.
