(2.) What was the design of having this bargain made. It was to signify that though Jerusalem was now besieged, and the whole country was likely to be laid waste, yet the time should come when houses, and fields, and vineyards should be again possessed in this land, v. 15. As God appointed Jeremiah to confirm his predictions of the approaching destruction of Jerusalem by his own practice in living unmarried, so he now appointed him to confirm his predictions of the future restoration of Jerusalem by his own practice in purchasing this field. Note, It concerns ministers to make it to appear in their whole conversation that they do themselves believe that which they preach to others; and that they may do so, and impress it the more deeply upon their hearers, they must many a time deny themselves, as Jeremiah did in both these instances. God having promised that this land should again come into the possession of his people, Jeremiah will, on behalf of his heirs, put in for a share. Note, It is good to manage even our worldly affairs in faith, and to do common business with an eye to the providence and promise of God. Lucius Florus relates it as a great instance of the bravery of the Roman citizens that in the time of the second Punic war, when Hannibal besieged Rome and was very near making himself master of it, a field on which part of his army lay, being offered to sale at that time, was immediately purchased, in a firm belief that the Roman valour would raise the siege, lib. ii. cap. 6. And have not we much more reason to venture our all upon the word of God, and to embark in Zion's interests, which will undoubtedly be the prevailing interests at last? Non si male nunc et olim sic erit—Though now we suffer, we shall not suffer always.
