Yahweh speaks directly via Isaiah about his love for Israel. His indignation at them will be short lived. In his anger, he will destroy the Assyrians with a whip. He will do this, just as he had helped the Israelites under Gideon against Oreb and the Midian people at the rock of Oreb in Judges, chapters 6-7. Then there is also an allusion to Yahweh’s staff at the parting of the Red Sea when the Israelites escaped from Egypt in Exodus, chapter 14. At that point, the burden on their shoulders and the yoke on their necks will be lifted.
A blow of the tongue is worse than a blow from a whip because the blow from the tongue crushes your bones, not merely a welt on your skin. This blow of the tongue is something that somebody has said that ruins your life. More people have fallen from this blow of the tongue than from the sword. You will be happy if you are protected from this blow from the tongue. If you have not been exposed to its anger or yoke, consider yourself happy. The blow of the tongue is like being put in bronze chains with an iron yoke on your neck. Hades would be preferable to the slow evil death from a blow of the tongue. Be careful when you say things about others.
Honor should not be given to fools because it is out of place, like snow in summer or rain at harvest time. Just like a sparrow or a swallow flitting and flying, an undeserved curse is useless. What works is a whip for a horse, a bridle for a donkey, and a whip for the back of fools. Fools are just slightly more valuable and tolerable than horses and donkeys.
