Ezekiel 36:20-22 Ezek. 36:20-22
20 And when they entered unto the heathen, whither they went, they profaned my holy name, when they said to them, These are the people of the LORD, and are gone forth out of his land. 21 But I had pity for mine holy name, which the house of Israel had profaned among the heathen, whither they went. 22 Therefore say unto the house of Israel, Thus saith the Lord GOD; I do not this for your sakes, O house of Israel, but for mine holy name's sake, which ye have profaned among the heathen, whither ye went.
Romans 2:24 Rom. 2:24
For the name of God is blasphemed among the Gentiles through you, as it is written.
