1 Corinthians:13.1 Though I speak with the tongues of men and of angels, but have not love, I have become sounding brass or a clanging cymbal.
The word tongues in the passage is the greek word glossa. Here is the Thayer Definition.
Thayer Definition: The language or dialect used by a particular people distinct from that of other nations
God divided the tongues of men in Gen 11:7. But in this passage, Paul uses the plural "tongues" in a way that suggests a multiplicity of languages among angels in the same way it exists among men.
QUESTION: 1) Did paul think angels differed in their tongues?
a) If yes, how could he have arrived at such a view.
b) Was there anything in the Pharisaical doctrines of the day to support his phrasing of 1-cor 13:1?
