Archeologists digging in northern Israel have discovered evidence of a 3,000-year-old beekeeping industry, including remnants of ancient honeycombs, beeswax and what they believe are the oldest intact beehives ever found.

The findings in the ruins of the city of Rehov include 30 intact hives dating to around 900 B.C.E., archaeologist Amihai Mazar of the Hebrew University of Jerusalem told The Associated Press. He sad it offers unique evidence that an advanced honey industry existed in the Holy Land at the time of the Bible.

Beekeeping was widely practiced in the ancient world, where honey used for medicinal and religious purposes as well as for food, and beeswax was used to make molds for metal and to create surfaces to write on. While portrayals of bees and beekeeping are known in ancient artwork, nothing similar to the Rehov hives has ever been found before, Mazar said.
