וַיֹּ֖אמֶר אָחָ֑ז לֹא־אֶשְׁאַ֥ל וְלֹֽא־אֲנַסֶּ֖ה אֶת־יְהוָֽה׃
But Ahaz said: ‘I will not ask, neither will I try the LORD.’
Rashi on Isaiah
and I will not test I do not wish that His Name be hallowed through Me.
Ibn Ezra on Isaiah
I will not ask, etc. From the answer of the prophet we conclude that the words of Ahaz must be taken in a bad sense: I shall not ask nor shall I try Him, for I know that He cannot do what I should ask Him.
