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 poetry in 22:6-10, 13-28, 28-30.
Because the king lived in luxury and oppressed the poor, God was sending him and his mother into captivity unless he repented. The king lacked justice. (See: [[rc://en/tw/dict/bible/other/oppress]] and [[rc://en/tw/dict/bible/kt/repent]] and [[rc://en/tw/dict/bible/kt/justice]])
