Some translations set each line of poetry farher to the right than the rest of the text to make it easier to read. 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]], [[rc://en/tw/dict/bible/kt/repent]] and [[rc://en/tw/dict/bible/kt/justice]])
