Easton's Bible Dictionary (1897)
A basalt stone, bearing an inscription by King Mesha, which was discovered at Dibon by Klein, a German missionary at Jerusalem, in 1868. It was 3 1/2 feet high and 2 in breadth and in thickness, rounded at the top. It consisted of thirty-four lines, written in Hebrew-Phoenician characters. It was set up by Mesha as a record and memorial of his victories. It records (1) Mesha’s wars with Omri, (2) his public buildings, and (3) his wars against Horonaim. This inscription in a remarkable degree supplements and corroborates the history of King Mesha recorded in 2 Kings 3:4-27.
With the exception of a very few variations, the Moabite language in which the inscription is written is identical with the Hebrew. The form of the letters here used supplies very important and interesting information regarding the history of the formation of the alphabet, as well as, incidentally, regarding the arts of civilized life of those times in the land of Moab. C. 900. ” It is the oldest inscription written in alphabetic characters, and hence is, apart from its value in the domain of Hebrew antiquities, of great linguistic importance.
