The Bible contains numerous references to Asherah or to “asherahs,” usually in the context of calls for their destruction or rebukes to those who worship them. It is not always clear whether the term refers to a female deity or ritual objects associated with that deity, which might have been statues, or poles thought to represent trees, or actual sacred trees. There are also competing theories about which Levantine deities were Asherah’s equivalent. And then there seem to have been those who worshipped both Asherah and the biblical God. Ellen White writes:
Inscriptions . . . contain the phrase “Yahweh and his Asherah.” Some take this to mean it was believed that she was seen as the wife of Yahweh and represents the goddess herself. Yet the presence of [the possessive “his”] could suggest that it is not a personal name. This has led others to believe it is a reference to the cult symbol. A more obscure opinion claims it means a cella or chapel; this meaning is found in other Semitic languages, but not Hebrew. Because of the similarities between [the pagan god] El and Yahweh, it is understandable that Asherah could have been linked to Yahweh. While some readers might find disturbing the idea that Yahweh had a wife, it was common in the ancient world to believe that gods married and even bore children. This popular connection between Yahweh and Asherah, and the eventual purging of Asherah from the Israelite cult, is likely a reflection of the emergence of monotheism from the Israelites’ previous polytheistic worldview.
