Helam - (Easton's Bible Dictionary)
Place of abundance, a place on the east of Jordan and west of the Euphrates where David gained a great victory over the Syrian army (2 Sam. 10:16), which was under the command of Shobach. Some would identify it with Alamatta, near Nicephorium.

he'-lam (chelam, 2Sa 10:16 f; in 16:17 with the he of locale; Septuagint Hailam): A place near which David is said to have defeated the Aramean world under Hadarezer (2Sa 10:16). Its site is unknown. Cornill and others introduce it into the text of Eze 47:16 from the Septuagint Heliam). This would place it between the territories of Damascus and Hamath, which is not unreasonable. Some scholars identify it with Aleppo, which seems too far north.
