V. yea, yea), expresses emphatic assertion, Mat_5:37; ἤτω ὑμῶν τό ναί ναί, let your ναί be ναί, i. e. let your allegation be true, Jas_5:12 (Buttmann, 163 (142); Winer's Grammar, 59 (58)); εἶναι or γίνεσθαι ναί καί οὐ, to be or show oneself double-tongued, i. e. faithless, wavering, false, 2Co_1:18 f; ἵνα παῥ ἐμοί τό ναί ναί καί τό οὐ οὐ, that with me should be found both a solemn affirmation and a most emphatic denial, i. e. that I so form my resolves as, at the dictate of pleasure or profit, not to carry them out, ibid. 17 (cf. Winer's Grammar, 460 (429)); ναί ἐν αὐτῷ γέγονεν, in him what was promised has come to pass, 2Co_1:19; ἐπαγγελίαι ἐν αὐτῷ τό ναί namely, γεγόνασιν, have been fulfilled, have been confirmed by the event, 2Co_1:20 (cf. Meyer at the passage). It is a particle of appeal or entreaty, like the (English yea) (German ja): with an imperative, ναί ... συλλαμβάνου αὐταῖς, Php_4:3 (where Rec. has καί for ναί); ναί ἔρχου, Rev_22:20 Rec.; so ναί ναί, Jdt_9:12. (A classification of the uses of ναί in the N. T. is given by Ellicott on Php_4:3; cf. Green, 'Grit. Note' on Mat_11:26.)
