Arnon

Hastings' Dictionary of the Bible

ARNON . A valley with a stream in its bed, now called Wâdy el-Môjib , which gathers the waters from many tributary vales the ‘wadys’ [AV [Note: Authorized Version.] ‘brooks,’ RV [Note: Revised Version.] ‘valleys’] of Arnon ( Numbers 21:14 ) as it flows westward to the Dead Sea. It was the N. border of Moab. cutting it off from the land of the Amorites in old time ( Numbers 21:13 etc.), and later, from that of the Eastern tribes ( Joshua 12:1 etc.). It is named in Isaiah 16:2 (‘the fords of Arnon’) and Jeremiah 48:20 (where the reference may be to the inhabitants of the valley, or to a city of that name now unknown). Mesha made the ‘high way in Arnon,’ and built (possibly ‘fortified’) Aroer (Moabite Stone). This ‘high way’ probably followed the line of the Roman road, traces of which still remain, with indications of a bridge, some distance W. of Aroer the modern ‘Ar‘âir , or ‘Ar‘ar , which stands on the N. bank.
