Some translations set poetry farther to the right than the rest of the text to show that it is poetry. The ULB does this with the poetic song in 6:12-13.
The second part of the chapter is about a crown made for the high priest. This is an actual person, but the meaning of the word "branch" should be translated as his name. (See: [[rc://en/tw/dict/bible/kt/highpriest]])
The visions are stated and even when the prophet asked for an explanation, their true meaning is often obscure. This uncertainty should remain in your translation. (See: [[rc://en/tw/dict/bible/kt/prophet]])
