From the Greek:
Ἐὰν ταῖς γλώσσαις τῶν ἀνθρώπων λαλῶ καὶ τῶν ἀγγέλων, ἀγάπην δὲ μὴ ἔχω, γέγονα χαλκὸς ἠχῶν ἢ κύμβαλον ἀλαλάζον.
1 If I should be speaking in the
languages of men
and of the messengers, yet should have no love, I have become resounding copper or a clanging cymbal.
and of the messengers, would appear to be meaning Angels, since men is listed alongside.
