Ezekiel is a book of prophecy and not exactly a lovely one. Ezekiel is at times a living object lesson, instructed to eat food cooked over excrement, divide up his hair into piles, calmly accept the death of his wife. He sees wheels and cherubim, living creatures, a valley of dry bones that come to life. He prophesies of a prince and a temple. He speaks against the surrounding nations as well as Israel.
The Israelites are depicted as a faithless woman, continually prostituting herself to others. It's an ugly, drawn-out picture.
But God isn't done with Israel and will change her from the inside out, just as He does with all His children.
