The first two words in Hebrew are the same two that opened 19:12, one chapter earlier.
Quick answer
Provoking a powerful man is not brave, it is expensive. The verse counts the cost to the provoker rather than judging the king.
Read both lines
The lion returns from 19:12, word for word at the start of the line, and the difference is where each verse goes next. There the roaring was paired with dew on the grass, and the point was that power has weather. Here there is no second weather, only the consequence. The NKJV footnotes "wrath" as literally fear or terror, which sharpens it: the thing described is not the king's feeling but the dread he produces. And the last phrase says the provoker sins against his own nephesh, his own life, which is the verse's actual claim. Nothing here says the king is right. It says the collision has a predictable outcome and only one party absorbs it.
