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 11:1-3, 17.
This chapter uses an extended metaphor of sheep and shepherds to represent Yahweh's dismay at the leaders during the exiles. (See: [[rc://en/ta/man/jit/figs-metaphor]])
The writer uses symbolism. Zechariah is told to become a shepherd. He uses two staffs and names them "Unity" and "Favor." He does this very purposefully. In order to preserve this symbolism, it is important to pay attention to the specific words used. (See: [[rc://en/tw/dict/bible/kt/favor]])
