The children of Judah and the children of Israel will be gathered together, and they will appoint themselves one head, and will go up from the land; for great will be the day of Jezreel.
He afterwards subjoins, They shall ascend from the land. He expresses more than at the beginning of the verse; for he says, that God would restore them from exile to their own country. He then promises what was very necessary, that exile would be no hindrance to God to renew his Church; for it was the people’s ruin to be removed far from their country, and consequently to be deprived of their promised inheritance during their dispersion among heathen nations. The Lord then takes away this difficulty, and distinctly declares, that though for a time they should be as wholly destroyed, they shall yet come again to their own land. They shall, therefore, ascend (this is said with regard to Judea, for it is higher than Chaldea) they shall, therefore, ascend from Chaldea and other places in which they had been dispersed. We now understand what the Prophet means by saying, Gathered together shall be the children of Israel and the children of Judah that is, into one body; and further, they shall appoint for themselves one head. This is the manner of the gathering; and it must be also added, that the Church then obeys God, when all, from the first to the last, consent to one head: for it is not enough to be constrained, unless all willingly offer themselves to Christ; as it is said Psalms 110:3, “There shall be a willing people in the day in which the King will call his own.’ Then the Prophet intended to express the obedience of faith, which the faithful will render to Christ, when the Lord shall restore them.
