The reference to Asherah in the Bible is referring to the wife of Baal which was a common pagan deity amongst the other inhabitants of this area. The only reason why there would be artifacts related to Asherah amongst the Israelites would be from one of their many descents into pagan idol worship. This would also correspond to an increase in Baal worship, the desecration of the temple, and a shift away from worshiping the Jewish Yahweh as their only God. I would have liked to think that a claim of such a magnitude would have been better researched to avoid the disgrace of such easily refutable error.

 Don't get all worked up over this.  It neither proves nor disproves anything about Judeo-Christian belief systesm.

"Asherah" is a cognate of an ancient proto-Indo-European term which appears in various languages as "Aesir" in proto-Germanic, "Asura" in Vedic pre-Indian texts, "Azera" in proto-Iranian texts.

Some linguists state that Osiris is also a Cognate of the same word.
