Five have no forgiveness of sins:—(1.) He who keeps on sinning and repenting alternately; (2.) he who sins in a sinless age; (3.) he who sins on purpose to repent; (4.) he who causes the name of God to be blasphemed. The fifth is not given in the Talmud.

Rabbi Yossi said:—"Never once in all my life have the walls of my house seen the hem of my shirt; and I have planted five cedars (sons are figuratively so termed, see Ps. xcii. 12) in Israel—namely, Rabbis Ishmael, Eliezar, Chalafta, Artilas, and Menachem. Never once in my life have I spoken of my wife by any other name than house, and of my ox by any other name than field."
