Isaiah 41:21 - Exposition

Produce your cause . The nations had been told to "draw near"—to "keep silence" while God spoke—and "then to speak" ( Isaiah 41:1 ). Now the time for them to speak is come, and they are challenged to " produce " and plead "their cause." Your strong reasons; literally, your bulwarks , or defences. Saith the King of Jacob. The king and tutelary god of the nation, Israel, really holding the position that the idol-gods were regarded as holding towards the peoples that worshipped them. The "kingly" character of the idol-gods was indicated in such names as Moloch (equivalent to "king"), Melkarth (equivalent to "king of the city"), Adrammelech (equivalent to "glorious king"), Baal (equivalent to "lord"), Adonis (equivalent to "my lord"), etc.
