Jeremiah 3:14

I will take you one of a city, and two of a family - If there should be but one of a city left, or one willing to return, and two only of a whole tribe, yet will I receive these, and bring them back from captivity into their own land. I have heard these words most sinfully applied to show the nature of a fancied eternal decree of election, that has appointed in several cases one only out of a whole city, and two out of a whole family, to be eternally saved, leaving the rest, according to the decree of reprobation, to perish everlastingly! And yet these persons, who spoke thus of the Fountain of eternal goodness and mercy, professed to believe in Him who by the grace of God tasted death for every man.

Children ... married - The twofold relationship gives a double certainty of acceptance. As children, they were sure of a father's love, as a wife they might hope for a revival of past affection from the husband of their youth.

One of a city, and two of a family - The family (in Hebrew) is far larger than a city, as it embraces all the descendants of a common ancestor. Thus, the tribe of Judah was divided into only four or five families. However national the apostasy, it does not involve in its guilt the few who are faithful, and the promises are still their rightful possession.

To Zion - To the true Church. The fulfillment of the promise began with the return to Palestine after the Babylonian exile, but is complete only in Christianity.

3:14 I am married - I am in covenant with you, and this covenant notwithstanding all your unfaithfulness, I am ready to renew with you.Family - This word is taken frequently for a country or nation, and this may partly respect the fewness of those that will return.But chiefly it respects God's exact care of them, that being now married to them, there shall not be one in a city, or two in a country or tribe, but he will find them out. Zion - The ten tribes did never return into their own land, therefore this must be understood of a spiritual going up to Zion, when all Israel shall be saved, Romans 11:26 .
