'Wherewith' in the Bible

And this shall be the plague wherewith Jehovah will smite all the peoples that have warred against Jerusalem: their flesh shall consume away while they stand upon their feet, and their eyes shall consume away in their sockets, and their tongue shall consume away in their mouth.

And if the family of Egypt go not up, and come not, neither'shall it be upon them; there shall be the plague wherewith Jehovah will smite the nations that go not up to keep the feast of tabernacles.
