Mishnayos Eruvin Perek 3 Mishnah 2

One may establish an eiruv with demai, produce purchased from one who may not have separated the required tithes, and similarly, one may establish an eiruv with the first tithe whose teruma has been taken in order to be given to a priest, and with the second tithe and consecrated articles that have been redeemed; and priests may establish an eiruv with ḥalla, the portion of dough that must be given to a priest. However, one may not establish an eiruv with tevel, produce from which the priestly dues [teruma] and other tithes have not been separated, nor with first tithe whose teruma, which must be given to a priest, has not been taken, nor with the second tithe or consecrated articles that have not been redeemed. If one sends his eiruv in the hands of a deaf-mute, an imbecile, or a minor, all of whom are regarded as legally incompetent, or in the hands of one who does not accept the principle of eiruv, it is not a valid eiruv. But if one told another person to receive it from him at a specific location and set it down in that spot, it is a valid eiruv. The critical point in the establishment of an eiruv is that it must be deposited in the proper location by a competent person; but it is immaterial how the eiruv arrives there.
