1:6 to knowledge, self-control; to self-control, perseverance; ¹  to perseverance, godliness;

2 Peter 2:19

2:19 Although these false teachers promise ²  such people ³  freedom, they themselves are enslaved to ⁴  immorality. ⁵  For whatever a person succumbs to, to that he is enslaved. ⁶ 

[1:6]  ¹ tn Perhaps “steadfastness,” though that is somewhat archaic. A contemporary colloquial rendering would be “stick-to-it-iveness.”

[2:19]  ² tn Verse 19 is a subordinate clause in Greek. The masculine nominative participle “promising” (ἐπαγγελλόμενοι, epangellomenoi) refers back to the subject of vv. 17-18. At the same time, it functions subordinately to the following participle, ὑπάρχοντες (Juparconte", “while being”).

[2:19]  ³ tn Grk “them.”

[2:19]  ⁴ tn Grk “slaves of.” See the note on the word “slave” in 1:1.

[2:19]  ⁵ tn Or “corruption,” “depravity.” Verse 19 constitutes a subordinate clause to v. 18 in Greek. The main verbal components of these two verses are: “uttering…they entice…promising…being (enslaved).” The main verb is (they) entice. The three participles are adverbial and seem to indicate an instrumental relation (by uttering), a concessive relation (although promising), and a temporal relation (while being [enslaved]). For the sake of English usage, in the translation of the text this is broken down into two sentences.

[2:19]  ⁶ tn Grk “for by what someone is overcome, to this he is enslaved.”
