isaiah 45:21 Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me. - Free Bible Online

      take counsel together--as to the best arguments wherewith to defend the cause of idolatry.
      who . . . from that time-- (Isa 41:22, 23; see on Isa 44:8). Which of the idols has done what God hath, namely, foretold, primarily as to Cyrus; ultimately as to the final restoration of Israel hereafter? The idolatry of Israel before Cyrus' time will have its counterpart in the Antichrist and the apostasy, which shall precede Christ's manifestation.
      just . . . and . . . Saviour--righteous in keeping His promises, and therefore a Saviour to His people. Not only is it not inconsistent with, but it is the result of, His righteousness, or justice, that He should save His redeemed (Isa 42:6, 21; Ps 85:10, 11; Ro 3:26).
