Mofdingas: Malone changes this to the 'Ofdingas' for complex reasons. Nobody else does this, so I have elected to leave it, though he makes a compelling argument (pgs 186-187).
Ongendmyrgingas: Malone has this combined with the previous word to form the Ongendmyrgingum but neither Chambers nor the ASPR does this. If it were correct, it might be identical to the later Wiþmyrgingas in 116. Malone takes his cue from Rieger and Langenfelt in following the structure of 'Ongendþeow' and placing the Ongend as a prefix of the word. Because of the presence of the 'regular' Myrgings in this same stanza, I have opted for Malone's reading.
