1. One would not have expected, (1.) That a prophet should concern himself so far in the business of this world; but why not? Though ministers must not entangle themselves, yet they may concern themselves in the affairs of this life. (2.) That one who had neither wife nor children should buy land. We find (ch. xvi. 2) that he had no family of his own; yet he may purchase for his own use while he lives, and leave it to the children of his relations when he dies. (3.) One would little have thought that a prisoner should be a purchaser; how should he get money beforehand to buy land with? It is probably that he lived frugally, and saved something out of what belonged to him as a priest, which is no blemish at all to his character; but we have no reason to think that the people were kind, or that his being beforehand was owing to their generosity. Nay, (4.) It was most strange of all that he should buy a piece of land when he himself knew that the whole land was now to be laid waste and fall into the hands of the Chaldeans, and then what good would this do him? But it was the will of God that he should buy it, and he submitted, though the money seemed to be thrown away. His kinsman came to offer it to him; it was not of his own seeking; he coveted not to lay house to house and field to field, but Providence brought it to him, and it was probably a good bargain; besides, the right of redemption belonged to him (v. 8), and if he refused he would not do the kinsman's part. It is true he might lawfully refuse, but, being a prophet, in a thing of this nature he must do that which would be for the honour of his profession. It became him to fulfil all righteousness. It was land that lay within the suburbs of a priests' city, and, if he should refuse it, there was danger lest, in these times of disorder, it might be sold to one of another tribe, which was contrary to the law, to prevent which it was convenient for him to buy it. It would likewise be a kindness to his kinsman, who probably was at this time in great want of money. Jeremiah had but a little, but what he had he was willing to lay out in such a manner as might tend most to the honour of God and the good of his friends and country, which he preferred before his own private interests.
