They go to Tethbae, to the first settlements of the bishops, namely Ardagh. The king of Tethbae was feasting nearby. A churl in the king’s house had done a terrible thing. He let fall a valuable goblet belonging to the king, so that it smashed to pieces against the table in front of the king. The vessel was a wonderful one, it was one of the rare treasures of the king. He seized the wretch then, and there was nothing for him but death. One of the two bishops comes to beseech the king. ‘Neither shall I give him to anybody’, said the king, ‘nor shall I give him in exchange for any compensation, but he shall be put to death.’ ‘Let me have from you’, said the bishop, ‘the broken vessel.’ ‘You shall have that’, said the king. The bishop then brought it in his arms to Brigit, relating everything to her. ‘Pray to the Lord for us that the vessel may be made whole.’ She did so and restored it and gave it to the bishop. The bishop comes on the following day with his goblet to the king and [says]: ‘If your goblet should come back to you make whole’, said the bishop, ‘would the captive be released?.’ ‘Not only that, but whatever gifts he should desire, I would give him.’ The bishop shows him the vessel and speaks these words to the king: ‘It is not I who performed this miracle, but holy Brigit’.
