I'm wondering why Isaiah 10:27 states
And it shall come to pass in that day, that his burden shall be taken away from off thy shoulder, and his yoke from off thy neck, and the yoke shall be destroyed because of the anointing.
this is about the yoke of the Assyrians not about the Day of the LORD
Isaiah 10:
24 Therefore thus says the Lord GOD of hosts: “O my people, who dwell in Zion,
be not afraid of the Assyrians when they strike with the rod and lift up their staff against you as the Egyptians did.
25 For in a very little while my fury will come to an end, and my anger will be directed to their destruction.
26 And the LORD of hosts will wield against them a whip, as when he struck Midian at the rock of Oreb. And his staff will be over the sea, and he will lift it as he did in Egypt.
27 And in that day his burden will depart from your shoulder, and his yoke from your neck; and the yoke will be broken because of the fat.”
Matthew Henry give a commentary on this:
They shall be wholly delivered from the power of the Assyrian, and from the fear of it, (Isaiah 10:27). “They shall not only be eased of the Assyrian army, which is now quartered upon them and which is a grievous yoke and burden to them, but they shall no more pay that tribute to the king of Assyria which before this invasion he exacted from them (2Kings 18:14), shall be no longer at his service, nor lie at his mercy, as they have done; nor shall he ever again put the country under contribution.”
