One who is half slave and half a free man, works one day for his master and one day for himself, these are the words of Beis Hillel. Beis Shammai said to [Beis Hillel]: You have provided a solution for his master, but for [him] himself you have not pro-vided a solution! He is not able to marry a slavewoman, [and] he is not able [to mar-ry] a free woman. Shall he remain idle? But was not the world created only for propagation, as it is stated (Isaiah 45:18): He [God] did not create it [the world] to be desolate; He formed it to be inhabited? Rather, for the benefit of society, we force his master and he [must] make him a [com-pletely] free man, and [the slave must] write [him] a note for half his value. [Subsequently] Beis Hillel reversed [themselves] to [thenceforth] rule in accordance with [the view of] Beis Shammai.
