Seder Nashim, Tractate Nedarim: Chapter 1, Mishnah 1
All the alternate forms of vows are like vows; those of haramim are like haramim; those of oaths are like oaths, and those of nazirite vows are like nazirite vows.
If one says to his fellow: "I am avowed from you", [or] "I am set apart from you," [or] "I stay away from you", "so that I do not eat of yours" or "so that I do not taste of yours,' he is prohibited. If he says: "I am banned to you," then Rabbi Akiva was hesitantly inclined to rule stringently.
