DISHON. 1. A chief among the Horites, the name sometimes rendered Dishan (Gen.36.21).
2. A great-grandson of Seir the Horite (Gen.36.25). The two may, however, be the same.
DISHON dī’ shŏn (דִּישֹׁ֑ון, דִישָׁ֑ן, דִּשֹׁ֑ן, LXX Δησων). Its meaning may be indicated by occurrence of the common noun, דִּישֹׁ֖ן in a list of clean animals which may be eaten (Deut 14:5). It is tr. in LXX with πυγαργον, which is the Libyan antelope. The RSV trs. “ibex”).
1. A chief of the Horites and fifth son of Seir whose land was appropriated by Esau and his descendants (Gen 36:21, 26, 30; 1 Chron 1:38, 41b).
2. A son of the Horite chief, Anah, and grandson of Seir. He was the brother of Oholibamah, Esau’s wife (Gen 36:25; 1 Chron 1:41a, 42). A comparison of Genesis 36:21-30 with 1 Chronicles 1:38-42 suggests the Dishan in Genesis 36:28 should be read Dishon (son of Anah). The LXX has Πισων.
