Notes on Ephesians 5:19: λαλοῦντες ἑαυτοῖς ψαλμοῖς καὶ ὕμνοις καὶ ᾠδαῖς πνευματικαῖς, ᾄδοντες καὶ ψάλλοντες τῇ καρδίᾳ ὑμῶν τῷ κυρίῳ, (WH 1881)
λαλοῦντες ἑαυτοῖς [ἐν] ψαλμοῖς καὶ ὕμνοις καὶ ᾠδαῖς πνευματικαῖς, ᾄδοντες καὶ ψάλλοντες τῇ καρδίᾳ ὑμῶν τῷ κυρίῳ, (NA28)
λαλοῦντες-present active participial form of λαλέω, "to speak." Rogers and Rogers also state that the "following four parts. [participles] indicate the outworking or practice of being filled w. the Spirit" (page 444). Compare Daniel B. Wallace, GGBB, pp. 639, 650-51.
Bengel's Gnomon: "ᾠδαῖς) songs, which are or may be sung on any sacred subject.—πνευματικαῖς, spiritual) not worldly, as those of the drunkards are."
See Richard A. Young, Intermediate New Testament Greek, p. 157 for Ephesians 5:19.
