μέλλω

future μελλήσω (Mt 24:6; and L T Tr WH in 2 Pet 1:12); imperfect ἔμελλον (so all editions in Lk 9:31 (except T WH); Jn 6:6, Jn 6:71 (except R G); (except T); (except L Tr); Acts 21:27; Rev 3:2 (where R present); (except L Tr)) and ἤμελλον (so all editions in Lk 7:2; Lk 10:1 (except R G); ; Jn 4:47; Jn 12:33; Jn 18:32; Acts 12:6 (exe. R G L); (except R G); (except R G T); Heb 11:8 (except L); cf. references under the word βούλομαι, at the beginning and Rutherford's note on Babrius 7, 15), to be about to do anything; so:
1. the participle, ὁ μέλλων, absolutely: τά μέλλοντα and τά ἐνεστῶτα are contrasted, Rom 8:38; 1 Cor 3:22; εἰς τό μέλλον, for the future, hereafter, Lk 13:9 (but see εἰς, A. II. 2 (where Grimm supplies ἔτος)); 1 Tim 6:19; τά μέλλοντα, things future, things to come, i. e., according to the context, the more perfect state of things which will exist in the αἰών μέλλων, Col 2:17; with nouns, ὁ αἰών ὁ μέλλων, Mt 12:32; Eph 1:21; ζωῆς τῆς νῦν καί τῆς μελλούσης, 1 Tim 4:8; τήν οἰκουμένην τήν μέλλουσαν, Heb 2:5; τῆς μελλούσης ὀργῆς Mt 3:7; τό κρίμα τό μέλλον, Acts 24:25; πόλις, Heb 13:14; τά μέλλοντα ἀγαθά, Heb 9:11 (but L Tr marginal reading WH text γενομένων); ; τοῦ μέλλοντος namely, Ἀδάμ, i. e. the Messiah, Rom 5:14.
