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 12:5-6, which is from the Old Testament.
God wants his people to do what is right. When they do what is wrong, he needs to correct or punish them. He does this just as earthly fathers correct and punish children whom they love. (See: [[rc://en/tw/dict/bible/kt/discipline]])
