Isaiah continues to describe the time when God will save the people of Israel. Although these events will happen in the future ([Isaiah 9:1](./01.md)), Isaiah describes them as if they have already happened. This emphasizes that they certainly will happen. (See: [[rc://en/ta/man/jit/figs-pastforfuture]])
Isaiah speaks of the Israelites, who are the Assyrians' slaves, as if they were an ox wearing a yoke. This will happen in the future, but he speaks as if it has already happened. Alternate translation: "For as on the day of Midian you will set the people of Israel free from being slaves to their oppressors like a person removes a yoke from the shoulders of an animal" (See: [[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/ta/man/jit/figs-pastforfuture]])
Isaiah speaks of the people of Israel as if they were one man. Alternate translation: "For the yoke of their burden ... their shoulders ... their oppressor" (See: [[rc://en/ta/man/jit/figs-metaphor]])
Another possible meaning is "staff," a long piece of wood that a person uses to beat the oxen so they will work and a symbol of one person's power to rule other people.
Isaiah speaks of the power the oppressor has over the people of Judah as if it were the piece of wood used by a person to beat oxen so they will work. (See: [[rc://en/ta/man/jit/figs-metaphor]])
The word "day" is an idiom that can refer to an event that takes more than one day to happen. Alternate translation: "as when you defeated the Midianites" (See: [[rc://en/ta/man/jit/figs-idiom]])
