Isaiah 43:26

Put me in remembrance - That is, urge all the arguments in your own defense which you can urge. State everything in self-vindication which can be stated. The language here is taken from the practice of courts when a cause is on trial; and God urges them on their side, to urge all in self-vindication which they can urge. On his part, he alleged that the princes and rulers of the nation had sinned Isaiah 43:27; that the whole nation had transgressed Isaiah 43:23, and that for this they were justly punished Isaiah 43:28. He here urges them to advance all in self-defense which they could - if they could pretend that He had forgotten anything; that they had merits which he had not considered; or that he had charged them with crime with undue severity.

Let us plead together - Hebrew, ‘Let us be judged together’ (see the note at Isaiah 41:1).

Declare thou, that thou mayest be justified - That you may show that you are just, or righteous; that you may demonstrate that you are unjustly accused of crime, and punished with undue severity.
