Sforno on Leviticus 22:32/ספורנו על ויקרא כ״ב:ל״ב

1ולא תחללו את שם קדשי, seeing that you the priests of all people are more aware than anyone of the perfection of My works, if you do not take care not to deviate from My commandments, this would be the greatest desecration of My holy name. The verse is reminiscent of Ezekiel 36,20 where the prophet laments that the exiles who come to host countries behave in such a way that the leaders of the host countries exclaim in dismay that surely these cannot the people of whom they have heard that they emulate the ways of their G’d!

2ונקדשתי בתוך בני ישראל, to continue to perform miracles for them as I had vowed to do when I said in Exodus 34,10 “I shall display miracles in the presence of your whole nation as proof that אני ה' מקדשכם, I, the Lord sanctify you.”
