know that I am Yahweh

When Yahweh says that people will know that he is Yahweh, he is implying that they will know that he is the one true God who has supreme authority and power. See how you translated this in Ezekiel 6:7. Alternate translation: "understand that I am Yahweh, the one true God" or "realize that I, Yahweh, have supreme power and authority" (See: rc://en/ta/man/jit/figs-explicit)

all the abominations that they have done

The abstract noun "abominations" can be stated as "things I hate." Alternate translation: "all the things they have done that I hate" (See: rc://en/ta/man/jit/figs-abstractnouns)

they have done

"the people have done"
