The question as to whether female angels exist has never been specifically addressed in biblical texts ( and I don't really care ), Angels are by definition neither male nor female in a human sense, they are a separate order of beings entirely. Still, when biblical writers try to describe angelic appearances, they consistently used masculine pronouns and male attributes. However, in Zechariah 5:9, the priest / scribe notes that two winged females take a woman named "wickedness" away to Babylonia in a measuring basket. Whilst contextually speaking "wickedness" is (hopefully) an 'anthropomorphic personification' rather than an actual individual (if she was, I know I dated her once), the two creatures transporting her, having wings "like those of a stork" are functioning in a typically angelic way, and are clearly described as female. In Jewish occult lore, female angels are rare (the Shekinah, 'the liberating Angel' is one). In Gnostic lore there is, pre-eminently, the revered Pistis Sophia, a great female aeon / archon, or angel. In Arabic legend, female angels are not uncommon and were often objects of worship or veneration; they were called "benad hasche", translated as Daughters of God.
