Abaye asked, But let's also consider one who removes the Choshen [breastplate] from the Eiphod [apron] and one who removes the poles from the Ark, which has its azhara from here: (Exodus 25,16) "You shall not remove them" and (Exodus 28,28) "And you shall loosen the Choshen".

Rav Ashi asked, But let's also consider one who plow with wood from an Asheia tree, which has its azhara from here: (Deuteronomy 13,8) ""And no abominable thing should cleave to your hand. etc."

Ravina asked, But let's also consider one who cuts down fruit bearing trees, which has its azhara from here: (Deuteronomy 20,19) "For you may eat from them, but you may not cut them down".

Rebbi Zeira asked to Rebbi Mani But let's also consider one who made a vow not to plow on Yom Tov? [Rebbi Mani answered,] There, the vow does not go into effect because it stands against what was sworn at Mount Sinai. [Rebbi Zeira] said to him, How about if he swore to not plow whether on a weekday or on Yom Tov, that since the oath takes effect on weekday, it also takes effect on YomTov? The mishna does not teach things that are subject to annulment.
