Komentarz do Diwrej ha-jamim II 32:31

And so, because of the emissaries of Heb. בִּמְלִיצֵי, messengers, similar to (Gen. 42:23): “for the interpreter (הַמֵּלִיץ) was between them” because the messenger is the liaison between the sender and the one to whom he is sent. This is related to the verse that states: “and Hezekiah prospered in all his work,” and after all this good, which the Holy One, blessed be He, had bestowed on him, God forsook him to test him, to know what was in his heart through the emissaries of the officers of Babylon, who were sent to him.

to seek the sign that was in the land He did not stand up to the test, and he showed them the weakness of his whole house. The verse is to be explained as if the phrases are reversed.
