Why does the Constitution specifically define treason?

To ensure a narrow and precise scope.

Article III, Section 3 states that, “Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort. No Person shall be convicted of Treason unless on the Testimony of two Witnesses to the same overt Act, or on Confession in open Court.”
