Isaiah's final(?) prophecy against Ephraim (Isaiah 28)

God sent Amos, Micah, Hosea, and Isaiah each to prophecy about the full destruction of the northern kingdom. They each prophesied at about the same time. This was after the legacy of Elijah and Elisha.

The destruction of the northern kingdom was a very big deal, which is why I think God appointed several prophets to arise at once.

Isaiah 28 covers the last "woe" about Ephraim. Isaiah tended to state things as "woe" whereas Hosea clearly focused on the adultery theme.

Isaiah 28 begins harsh, but turns to the redemptive. It focuses on the glory of God that will be evident on the remnant of Ephraim. It likes the whole process to the grinding of grain to make bread. God is already looking ahead to what will arise afterwards. However, it also means that it has already been full decided - Israel will be ground into flour to make bread.

Woe to the grains!
