The Aramaic word achoran (אָחֳרָן) is the Aramaic equivalent of Hebrew acher, meaning 'other' or 'another.' It appears in the Aramaic sections of Daniel to contrast false gods with the one true God.
The Aramaic sections of Daniel (chapters 2-7) were written for an international audience, addressing the Babylonian and Persian empires directly in their lingua franca. The word achoran appears in contexts where Daniel distinguishes between the God of Israel and 'other' gods — or where Gentile kings encounter the absolute uniqueness of Israel's God. This pluralistic context — 'another god' among many — is precisely the arena in which the true God demonstrates His sovereignty. God's power is not diminished by the presence of idols; rather, He triumphs over them repeatedly in Daniel's narrative.
