Ezekiel 36:20

And when they entered unto the heathen whither they went, when they were taken away into captivity, they profaned My holy name, by the open manner of sinning which was found ill their midst, when they, namely, the heathen, said to them, These are the people of the Lord and are gone forth out of His land. The sinful behavior of the Jews in tile various lands of their captivity caused the heathen who witnessed this behavior to blaspheme the name of Jehovah as being responsible for the trespasses. Cf Romans 2:24. There is great responsibility resting upon believers everywhere, that they make use of tact and care at all times, lest on their account the enemies of the Lord be made to mock the name of the one true God.
