  Ní du ṡémigud pectha at·ber-som inso .i. combad dó fa·cherred: “ní sní cetid·deirgni ⁊ ní sní dud·rigni nammá”; acht is do chuingid dílguda dosom, amal du·rolged dïa aithrib íar n‑immarmus.
  It is not to palliate sin that he says this, i.e. so that he might put it for this: “we have not done it first and we have not done it only”; but it is to seek forgiveness for himself, as his fathers had been forgiven after sinning.
