‘Again the word of Yahweh came to me, saying, “Son of man, cause Jerusalem to know her abominations.” '
God will now recount Israel's great sin and apostasy, to show her the greatness of the sin that she has committed. ‘Abominations' especially as in mind idolatry but anything that possesses a man's mind and comes between him and God is abomination.
(In Ezekiel the terms ‘Jerusalem', ‘Judah', and ‘Israel' are almost synonymous. What applies to one usually applies to the other. All are seen as one).
