The New Scofield KJV (1967) version, contains "RAM". The Old Scofield, Scofield lll, Thompson Chain, Cambridge, A no name KJV I have, even the NASB, and the Amplified Bible, contain ARAM.
The NKJV, NIV, RSV, like the 1967 Scofield KJV contain RAM. So we must conclude it is not an Alexanderian Boo Boo, since the NASB, or Amplified do not contain RAM. But the work of some unknown corrupter of later vintage.
So by majority rule, Aram has to be correct.
