Talmud zu Jirmejahu 31:5

MISHNAH: How does one bring First Fruits? All villages in the ma‘amad¹²The district which sent Temple personnel and accompanying laymen to Jerusalem for a week; cf. Berakhot Chapter 1, Note 231. district come to its central city. They stay overnight in the city square and do not enter houses¹³So as not to become impure by the impurity of the dead which persists for seven days. The impurity of the dead is transmitted by the “tent” (the house) over the corpse (Num. 19). Any other impurity is immediately removed by immersion in a miqweh outside the Temple mount and does not prevent the farmer from presenting his First Fruits.. In the morning, the organizer says to them (Jer. 31:5): “Get up and let us ascend to Zion, to the Eternal’s, our God’s, House.¹⁴In the verse: אל י^יי אלהינו.”
