Matius 16:18

16:18 And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades ¹  will not overpower it.

Matius 24:22

24:22 And if those days had not been cut short, no one would be saved. But for the sake of the elect those days will be cut short.

[16:18]  ¹ tn Or “and the power of death” (taking the reference to the gates of Hades as a metonymy).

[16:18]  sn In the OT, Hades was known as Sheol. It is the place where the unrighteous will reside (Matt 11:23; Luke 16:23; Rev 20:13-14). Some translations render this by its modern equivalent, “hell”; others see it as a reference to the power of death.
