Albert Barnes Commentary Numbers 23:7

"And he took up his parable, and said, From Aram hath Balak brought me, The king of Moab from the mountains of the East: Come, curse me Jacob, And come, defy Israel." — Numbers 23:7 (ASV)

Aram - Or, “highland.” This term denotes the whole elevated region, from the northeastern frontier of Palestine to the Euphrates and the Tigris. The country between these streams was especially designated “Aram-naharaim,” or “Aram of the two rivers:” the Greeks called it Mesopotamia; and here, according to (Deuteronomy 23:4), was Balaam’s home. Compare (Numbers 22:5) note.
