The oath as set out in the letter to the king differs from another copy of the oath, which immediately precedes the letter in Letter Book H, fos. 220b, 221; a clause having been subsequently added to the latter to the effect that the swearer abjured the opinions of Northampton and his followers, and would oppose their return within the bounds and limits set out in the king's letters patent.
