ייִדישער מחשבֿה אויף ירמיהו 32:5

From the above, it follows that being given the land of Israel and all the material wealth that this entailed, was a prerequisite for Israel to attain its spiritual objectives both nationally and individually. Cleaving to one's piece of land as a basis for one's financial security therefore, became very important. Pious people's habit of jealously guarding what is rightfully theirs, is understandable for that very reason. Also, the Torah seems especially protective about the material wealth of religious leaders. The reason is to shield them against temptation to acquire wealth by dubious means. If halachah teaches that a High Priest or prophet must be of independent means, or even be given that financial independence, this reflects the idea just discussed. It seems strange that the prophet Jeremiah is asked to waste his money by redeeming the land of an impecunious uncle, when such land is doomed to fall into the hands of foreigners. (Jeremiah 32,5-15) Although Jeremiah is not specifically commanded to purchase that piece of land to forestall it falling into the hands of his uncle's creditors, the thrust of the story is clearly that it was expected of him. Jeremiah, by his action, teaches that he carefully abided by what he perceived to be the will of G'd, even if there was room to doubt the matter. Also, Jeremiah was prepared to spend any amount of money to fulfil G'ds will, since he was certain that G'd would not want him to waste his money. Having done what he perceived to be G'ds will, he asked for some illumination. This was because he wanted to be certain that what he had done did indeed correspond to G'ds wishes. G'd told him that he had indeed interpreted His will correctly, that the money was not wasted however, since the eventual return to Zion was just as certain as the destruction which was about to happen. (verses 37-44)
