The word "yourselves" refers to the people of Jerusalem. Why they are astonished can be made explicit. Alternate translation: "Be astonished at what I am telling you" (See: [[rc://en/ta/man/jit/figs-explicit]] and [[rc://en/ta/man/jit/figs-doublet]])
The people ignoring what Yahweh says is spoken of as if they would make themselves blind. Alternate translation: "keep being ignorant and spiritually blind to what I am showing you" (See: [[rc://en/ta/man/jit/figs-metaphor]])
The people being senseless and not understanding what Yahweh is doing is spoken of as if they were drunk. Alternate translation: "Be senseless like a drunk person, but it is not because you have drunk too much wine or strong drink" (See: [[rc://en/ta/man/jit/figs-metaphor]])
