2 Peter 3:13 New English Translation

¹³But, according to his promise, we are waiting for^[a] new heavens and a new earth, in which^[b] righteousness truly resides.^[c]

2 Peter 3:13 tn Or possibly, “let us wait for.” The form in Greek (προσδόκωμεν, prosdokōmen) could be either indicative or subjunctive. The present participle in v. 14, however, is best taken causally (“since you are waiting for”), suggesting that the indicative is to be read here.
2 Peter 3:13 tn The relative pronoun is plural, indicating that the sphere in which righteousness dwells is both the new heavens and the new earth.
2 Peter 3:13 tn Grk “dwells.” The verb κατοικέω (katoikeō) is an intensive cognate of οἰκέω (oikeō), often with the connotation of “taking up residence,” “settling down,” being at home,” etc. Cf., e.g., Matt 2:23; Acts 17:26; 22:12; Eph 3:17; Col 1:19; 2:9. Hence, the addition of the adverb “truly” is implicit in the connotation of the verb in a context such as this.
