Rashi
and I will no longer cause My Holy Name to be profaned For Israel’s degradation is a profanation of His Name, “inasmuch as it is said of them, ‘these are the people of the Lord’” (above 36:20), and He is unable to save them.
Tze'enah Ure'enah
“I will make My holy name known” [39:7]. I will make my Holy name known to the nations. I will not profane My name further. When Israel are humiliated in exile, the nations say that their God does not have the power to redeem them and to protect them from our hands. Therefore, the Holy One said: the day has come that I have spoken of.3Rashi, Ezekiel, 39:7
