The (circa. 3rd Century C.E.) Hebrew Tosefta, ( Shabbat 13:5 ), quoting Rabbi Tarfon or Tarphon, Heb., ( רבי טרפון ), from the Gk., ( Τρύφων ), a Kohen, a member of the third generation of the Mishnah sages, who lived in the period between the destruction of the Second Temple ( 70 C.E. ) and the fall of Bethar ( 135 C.E. ):
SHABBAT 13:5: “...The [ Gilyohnim ] blank spaces and the Books of the Minim, we may not save them from a fire. R. Jose said: On weekdays one must cut out the [ Tetragrammaton ] Divine Names which they contain, hide them, and burn the rest. R. Tarfon said: May I bury my son if I would not burn them together with their [ Tetragrammaton ] Divine Names if they came to my hand...” - (Translated By Dr. H. Freedman as quoted on Page 30-31, The Watchtower, November 1, 1993.)
SHABBAT 13:5: “...The 'Gilyon[im]' and the [Biblical] books of the Judæo-Christians [ Minim ] are not saved [on the Sabbath] from fire; but one lets them burn together with the [ Tetragrammaton ] names of God written upon them." R. Jose the Galilean says: "On week-days the [ Tetragrammaton ] names of God are cut out and hidden while the rest is burned." R. Tarphon says: "I swear by the life of my children that if they fall into my hands I shall burn them together with the [ Tetragrammaton ] names of God upon them." R. Ishmael says: "If God has said, 'My name that has been written in holiness [i.e., in the "jealousy roll" mentioned in Num. v. 21 et seq.] shall be wiped out by water, in order to make peace between husband and wife,' then all the more should the books of the Judæo-Christians, that cause enmity, jealousy, and contention between Israel and its heavenly Father. [...] As they are not saved from fire, so they are not saved when they are in danger of decaying, or when they have fallen into water, or when any other mishap has befallen them...” - (Page 29, Zuckermandel, Edition, “GILYONIM = “Gospels,” lit., “scrolls,” JEWISH ENCYCLOPEDIA ONLINE.)
