THE BIBLE PLACES BLOG: Artifact of the Month: Mesha Stela (Moabite Stone). Looking through the PaleoJudaica archive, I am surprised that the Moabite Stone inscription hasn't been received more attention here. But a couple of posts dealing with it are here and here. And here's a Bible History Daily post from October 2013 which I seem to have missed: The Importance of Bible Artifacts Found Outside the Trench: The Moabite Stone.
