Acts 1:7 It is not for you to know the times or the seasons,

The original Greek emphasizes that fact that the Father has put this information under his own authority alone. The verb "put" is a middle voice, which means he put it for himself or by himself., This idea is reemphasized by the use of the "his own" adjective to describe his "authority" or "power." This is further emphasized by the use of an article, "this his own authority," which is untranslated in all English translations because it seem so exaggerated.
