Confirmation of an exchange

Translated letter:

In the name of the Holy and Individual Trinity, amen. Therefore, let every church rejoice strengthened in her own right by boundaries of peace. We Bolesław, son of Leszek by divine providence duke of Sandomierz together with our mother, lady Gremislava, with the agreement of the chapter of the church of Sandomierz and by the will of the brothers of the monastery of Wąchock make such an exchange between themselves, namely: that the church of Sandomierz should have part of the estate of Nicholas / Mikołaj son of Hugo, which lies next to the same city, while the monastery of Wąchock for its part should receive according to hereditary right possession of a certain portion which the church of Sandomierz used to have in Ostrów next to the rock. 
The present persons whose names are here both as actors [and] as witnesses were in attendance at this exchange: Martin, abbot of the aforementioned monastery, Matthew the deacon, Jaskor the provost of the church of Sandomierz, Salomon the scholar, Peter the cantor, canons John [and] Florian, Benedict the sub-chamberlain, Hartmann the doctor, the vicars Bartholomew, Matthew, Gabriel, John, Baldwin. 
And on the same day the said Nicholas / Mikołaj testified publicly that he accepted six marks of pure silver from the aforementioned abbot with the monastery of Wąchock and with the same witnesses for his donation and sale. 
Done in the year of the Lord 1243. These things were done in Sandomierz on the vigil of [the feast] of Blessed Benedict the Abbot [20 March with the feast day on 21 March].
