( Ἀμάν ), the Graecized' form ( Tobit 14:10; Esther 10:7, etc.) of the name HAMAN (See Haman) (q.v.).

Ama'na [many Am'ana] (Hebrew Amanahah', אֲמָנָה , a Covenant, as in  Nehemiah 10:1), the name of a river and of a hill.

1. The marginal reading (of many codices, with the Syriac, the Targum, and the Complutensian ed. of the Sept.) in  2 Kings 5:12, of the stream near Damascus called in the text ABANA (See Abana) (q.v.).

2. (Sept. Πίστις , Vulg. Amana.) A mountain mentioned in  Song of Solomon 4:8, in connection with Shenir and Hermon, as the resort of wild beasts. Some have supposed it to be Mount Amanus in Cilicia, to which the dominion of Solomon is alleged to have extended northward. But the context, with other circumstances, leaves little doubt that this Mount Amana was rather the southern part or summit of Anti-Libanus, and was so called perhaps from containing the sources of the river Amana or ABANA (See Abana) (q.v.). The rabbins, indeed, call Mount Lebanon various names (Reland, Paloest. p. 320), among which appears that of Amanon ( אֲמָנוֹן , Gittin, fol. 8, 1, v. r. וּמָנוּס , Umanus, or Matthew Hor, according to Buxtorf, Lex. Talm. col. 117).

International Standard Bible Encyclopedia [4]

ā´man ( Ἀμάν , Amán  ; Codex Vaticanus reads Ἀδάμ , Adám ): Tobit 14:10; Additions to Esther 12:6; 16:10, 17, probably in each case for Haman, the arch-enemy of the Jews in the canonical Book of Esther (compare  Esther 3:1 with Additions to Esther 12:6). In Additions to Esther (16:10) Aman is represented as a Macedonian, in all other points corresponding to the Haman of the Book of Esther.
