How do these passages impinge on succession or Korah?
Korah was a Levite who tried to usurp the authority of the High Priest Aaron and of Moses. For the NT, the believer is also a priest. One can take it from there.
What little I know about the claimed line of authority from the various parts of the body (RCC, EO, OO, Protestant) is twofold. One is the 'keys of the kingdom'. Two is the 'feed My sheep'.

The passages quoted from scripture clearly show for at least one of the claims where the authority went. Keep in mind that the apostles agreed that Peter went to the Jews, while Paul went to the Gentiles. As such, Peter turns it over to those in the dispersion, while Paul turned it over to those in Ephesus.
They assigned it to the elders of the church/flock, not to all, but to the elders (plural). In turn, they were supposed to transfer the same information, authority, and power, bringing up believers from baby to maturity/elder.
Acts 20:17 And from Miletus he (Apostle Paul) sent to Ephesus, and called the
