<p>4:37 <i>H</i><i>aving a field, sold it; and brought the money and laid it at the apostles' feet</i>- Perhaps he was motivated by how all Judas could buy for his pieces of silver was a field. He too had a field, held illegally before God. And he wanted to get rid of it quickly. He brought money cash for it to the apostles, whereas :34 speaks of others carrying the proceeds of what they sold as if those proceeds weren't simply cash. I would conclude from this that he sold the title deeds quickly, for a cheap price, to someone in Jerusalem. Otherwise we are to imagine him sailing to Cyprus, finding a buyer, and then returning- which at the speed business was done in the East, would've taken maybe a year. The field however may not have been in Cyprus.</p>
