Isaiah 41:21 - Matthew Poole's English Annotations on the Holy Bible

Produce your cause: the prophet having pleaded God's cause against the idolatrous Gentiles, whom he challenged to a dispute, Isaiah 41:1, he now reneweth the challenge, and gives them liberty and invitation to speak whatsoever they can on the behalf of their idols. Bring forth your strong reasons, to prove the divinity of your idols.
