In that you have brought into my sanctuary foreigners, uncircumcised in heart, and uncircumcised in flesh, to be in my sanctuary, to pollute it, even my house, when you offer my food, the fat and the blood, and they have broken my covenant because of all your abominations.
Read Chapter 44

Flesh. People of this description were not to enter the temple, which is here called the sanctuary, even though they adored God. In some cases pagans were admitted into any part, except the most holy. Epiphanes (Calmet) and Pompey forced their passage thither, to the great sorrow of the Jews. (Josephus, Jewish Wars i. 5.) See Ecclesiasticus lii., and Acts xxi. 28.
During the plundering of the city, the Chaldeans did the like; (Lamentations i. 10.; Haydock) and while idols were set up, all rules were neglected.
Doings. You observe the exterior, and not the spirit of religion.
