BAALSAMUS bā əl sā’ məs (Βααλσαμος). One of the seven men who stood on the right side of Ezra as he read the law to the people according to the Apoc. (1 Esd 9:43). In the parallel passage in Nehemiah, he is named Maaseiah (Neh 8:4).

International Standard Bible Encyclopedia (1915)

Baalsamos; (the King James Version Balasamus): B. stood at the right side of Ezra, when the law was read to the people (1 Esdras 9:43). Compare Maaseiah (Ne 8:7). the Valley of Rephaim where David obtained a signal victory over the Philistines; it was higher than Jerusalem for David asked, "Shall I go up against the Philis?" (2Sa 5:20; 1Ch 14:11). The exact site is unknown, but if the Vale of Rephaim is el Beka`a, the open valley between Jerusalem and Mar Elias, then Baal-perazim would probably be the mountains to the East near what is called the "Mount of Evil Counsel" (see Jerusalem). The Mount Perazim of Isa 28:21 would appear to be the same spot.
