'Whereby' in the Bible

the great trials which thine eyes saw, and the signs, and the wonders, and the mighty hand, and the outstretched arm, whereby Jehovah thy God brought thee out: so shall Jehovah thy God do unto all the peoples of whom thou art afraid.

Jehovah will send upon thee cursing, discomfiture, and rebuke, in all that thou puttest thy hand unto to do, until thou be destroyed, and until thou perish quickly; because of the evil of thy doings, whereby thou hast forsaken me.
