Because it is a trial, and what if the sword contemn even the rod? it shall be no more, saith the Lord GOD.

All they that take the sword, shall perish with the sword

Ye Ethiopians also, ye shall be slain by my sword.

For through the voice of the LORD shall the Assyrian be beaten down, which smote with a rod.

And there shall come forth a rod out of the stem of Jesse, and a Branch shall grow out of his roots.

And it shall come to pass, that him that escapeth the sword of Hazael shall Jehu slay: and him that escapeth from the sword of Jehu shall Elisha slay.
