A.T. Robertson Commentary 2 Peter 3:13

"But, according to his promise, we look for new heavens and a new earth, wherein dwelleth righteousness." — 2 Peter 3:13 (ASV)

Promise (επαγγελμα). As in 1:4. The reference is to Isa 65:17f.; 66:22. See also Re 21:1. For καινος (new) see on Mt 26:29. For the expectant attitude in προσδοκωμεν (we look for) repeated from verse 12 and again in verse 14, see απεκδεχομεθα (we eagerly look for) in Php 3:20.

Wherein (εν οις). The new heavens and earth.

Dwelleth (κατοικε). Has its home (οικος). Certainly "righteousness" (δικαιοσυνη) is not at home in this present world either in individuals, families, or nations.
