Bath Kol, commonly written Bat Kol, is a term for a heavenly voice in rabbinic literature. It is important to distinguish that concept from a named angel with an individual biography.
A heavenly voice in the Talmud
Sanhedrin 11a says that after the deaths of Haggai, Zechariah and Malachi, the Holy Spirit departed from Israel, yet people still received a heavenly voice. The passage includes an announcement identifying someone in an assembly as worthy of the divine presence.
In the Oven of Akhnai discussion in Bava Metzia 59b, a heavenly voice supports Rabbi Eliezer. Rabbi Joshua responds by invoking the principle that the Torah is not in heaven; the discussion concerns authority in deciding religious law.
Personification in an angel dictionary
Davidson’s later dictionary, under Bat(h) Qol, combines reports of divine pronouncement with a guardian-angel description and feminine imagery. That presentation should not turn every rabbinic occurrence of a voice into an encounter with an individual female angel.
