2 Petrus 1:5

1:5 For this very reason, ¹  make every effort ²  to add to your faith excellence, ³  to excellence, knowledge;

2 Petrus 3:18

3:18 But grow in the grace and knowledge ⁴  of our Lord and Savior Jesus Christ. To him be the honor both now and on ⁵  that eternal day. ⁶ 

[1:5]  ¹ tn The Greek text begins with “and,” a typical Semitism.

[1:5]  sn The reason given is all the provisions God has made for the believer, mentioned in vv. 3-4.

[1:5]  ² tn The participle is either means (“by making every effort”) or attendant circumstance (“make every effort”). Although it fits the normal contours of attendant circumstance participles, the semantics are different. Normally, attendant circumstance is used of an action that is a necessary prelude to the action of the main verb. But “making every effort” is what energizes the main verb here. Hence it is best taken as means. However, for the sake of smoothness the translation has rendered it as a command with the main verb translated as an infinitive. This is in accord with English idiom.

[1:5]  ³ tn Or “moral excellence,” “virtue”; this is the same word used in v. 3 (“the one who has called us by his own glory and excellence”).

[3:18]  ⁴ tn The term “knowledge” (γνῶσις, gnwsis) used here is not the same as is found in 2 Pet 1:2, 3, 8; 2:20. This term is found in 1:5 and 1:6.

[3:18]  ⁵ tn Or “until.”

[3:18]  ⁶ tc ‡ The vast bulk of mss add ἀμήν (amhn, “amen”) at the end of this letter, as they do almost all the rest of the NT books (only Acts, James, and 3 John lack a majority of witnesses supporting a concluding ἀμήν). The omission in B 1241 1243 1739* 1881 2298 appears to be original, although the fact that some of the best and earliest Alexandrian witnesses (Ì⁷² א A C P Ψ 33 co), along with the Byzantine text and early versions (vg sy), add the particle renders such a judgment less than iron-clad. NA²⁷ places the word in brackets, indicating doubts as to its authenticity.

[3:18]  tn Grk “day of eternity.”
