Ab´ana, or, as it is given in the marginal reading, Amana, the name of one of the rivers which are mentioned by Naaman (2 Kings 5:12), 'Abana and Pharpar,' as 'rivers of Damascus.' Amana signifies 'perennial,' and is probably the true name. At the present day it is scarcely possible to discover with certainty the stream to which this name was applied. The most recent conjecture seeks the Abana in the small river Fidgi, which rises in a pleasant valley fifteen or twenty miles to the north-west of Damascus and falls into the Barrada, the main stream by which Damascus is irrigated.
