is the principal source for angelic tongues at Qumran. The texts are fragmentary but appear to relate to praise tongues:

...The tongue of the first will be strengthened seven times with the tongue of the second to him....... 4Q403 1 2, 27-30
The pseudepigraphical Testament of Job contains a conclusion which is believed to relate to the compiling of the hymnbook used by a Therapeutae community. Job gives one of his daughters "a cord"
"And she took on another heart—no longer minded toward earthly things—but ecstatically in the angelic dialect, sending up a hymn to God in accord with the style of the angels. And as she spoke ecstatically, she allowed “The Spirit” to be on her garment."
Job’s other daughters likewise took on “the dialect of archons”, “the dialect of those and the “dialect of the cherubim”. The “cherubim” are also mentioned Songs of the Sabbath Sacrifice as blessing God. There is parallel description of sung prophecy among the Therapeutae in Alexandria by Philo, but no mention there of angelic tongues.
New Testament
A possible reference to Jewish practices of angelic tongues is 1Co13:1 "If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal." The distinction "of men" and "of angels" may suggests that a distinction was known to the Corinthians. If a distinction is intended then 1Co14:10 "There are doubtless many different languages in the world, and none is without meaning" may imply that "tongues of men" were intelligible, whereas 1Co14:2 For one who speaks in a tongue speaks not to men but to God; for no one understands him, but he utters mysteries in the Spirit." refers to angelic tongues. The problem with this is that the "angelic" tongues documented at Qumran and among the Therapeutae appear to be inspired, but coherent and intelligible, sung praise. Against this is the view of Dunn that "It is evident then that Paul thinks of glossolalia as language".
