Martyrdom of Isaiah.
There is a tradition that the prophet Isaiah suffered martyrdom by a saw. The ancient book entitled, "The Ascension of Isaiah the Prophet," accords with the tradition. It says: "Then they seized Isaiah the son of Amos and sawed him with a wooden saw. And Manasseh, Melakira, the false prophets, the princess and the people, all stood looking on. But he said to the prophets who were with him before he was sawn, 'Go ye to the country of Tyre and Sidon, for the Lord hath mixed the cup for me alone.' Neither while they were sawing him did he cry out nor weep, but he continued addressing himself to the Holy Spirit until he was sawn asunder."
