Please read the passage before reading the commentary
Nahum the prophet flourished around 621 BCE. His name means Compassionate One. We know little about him. The town of Capernaum includes his name, Caper-na(h)um, which means Nahum’s town. Capernaum, however, has no connection with the prophet Nahum so far as we know.
He seems to gloat over the destruction of Ninive. There was no love lost between the Israelites and the Ninevites, two very hostile cities to each other. Perhaps we could feel much the same was about Russia or, perhaps, the feelings of Republican and Democrats towards each other. Nahum asked who could pity Ninive; judging from his name and his words, Nahum would not pity her.
Nahum was a very human author and prophet. God sent him to console his people, and Nahum poured out all his negative feeling, all the anger and frustration of seeing David’s kingdom destroyed and annihilated. Nahum spoke the nation’s cathartic lamentation.
From this we can learn a few things. It is human to express anger, but we are not to let anger rule us. God can use angry people to do God’s work. God loves angry people. Sometimes we should express anger, but in healthy ways. God can fulfill God’s promises to us even though we be angry. If Nahum could be a prophet, then so can we.
