משנה על במדבר 6:15

Meisah: Bet Shammai exempts [from hallah], And Bet Hillel makes liable [for hallah]. Halita: Bet Shammai makes liable, And Bet Hillel exempts. The loaves of the thanksgiving sacrifice and the wafers of a nazirite: if one made them for oneself, they are exempt [from hallah]. [If one made them] to sell in the market, they are subject [to hallah].
