Jeremiah 31:8

When Jeremiah says, "And I will gather them together from the extremities of the land in the feast day," he signifies the day of the Passover and of Pentecost, which is properly a "feast day." However, every day is the Lord's. Every hour, every time, is apt for baptism. If there is a difference in the solemnity, there is no distinction in the grace.

The remnant of the people of Israel are gathered through the apostles and apostolic people, about whom we read above "guardians will call on the mountain" and to whom it was commanded to "sing and resound," that the remnant of Israel might be saved. The Lord also promises that he will bring them down from the north country, he who is "the most severe wind but is called the right hand," due to unbelief and the frigidity of his love. He also promises to gather them from the ends of the earth in no time other than the paschal solemnity, that is, in the days of the Lord's passion, when the Lord was crucified and when the gospel promise was fulfilled: "When I am lifted up, I will draw everyone to me." At that moment, he generated many people, fulfilling Isaiah's prophecy: "a people is born in one moment," for on one day, three thousand and five thousand people believed. It is also written in Hebrew, "among whom were the blind, the lame, the pregnant and women in labor together, a great gathering of those returning here."

(Verse 8) Behold, I will bring them from the land of the North, and gather them from the ends of the earth. What follows: In the solemnity of the Passover, he shall beget many sons, which is not found in Hebrew, but is only read in the Septuagint, for which it is written among the Hebrews: Among them will be the blind, and the lame, and the pregnant, and those giving birth together: the great Church of those returning here. The remaining people of Israel will be gathered by the Apostles and the apostolic men, of whom we read above: The custodians on the mountain will cry out, and to whom it is commanded: Resound, sing, and say, so that the remaining people of Israel may be saved. The Lord himself also promises to bring them back from the land of the North, which is a very harsh wind, but by the name of dexterous is called, from unbelief, from the coldness of the Lord's love; and to gather them from the ends of the earth, not at any other time, but on the solemnity of the Passover, that is, on the feast days of the Lord's passion: when the Lord was crucified, and that which he himself promised in the Gospel was fulfilled. When I am lifted up from the earth, I will draw all things to myself (John 12:23). Then he generated a great multitude, so that the prophecy of Isaiah might be fulfilled: For a nation has been born once (Isaiah 66:8). For on one day, three thousand believed, and on another day, five thousand men (Acts 2 and 4). And what is written in Hebrew: Among them will be the blind and the lame, and the pregnant and those giving birth together, a great church of those returning here; although it is also fulfilled according to the letter, that the blind will see, and the lame will walk: nevertheless, it can be better understood according to allegory, that those who were previously blind in faith, afterwards believed in the Savior; and those who were lame, to whom Elijah once spoke: How long will you limp on both feet (1 Kings 18:21)? Afterwards, they may have walked (Al. seen). And: The people who sat in darkness and the shadow of death have seen a great light. (Isaiah 9:2); the lame may have run, and the pregnant woman may have given birth to sons, the great Church of those who return to faith. The Jews imagine this to have been fulfilled when, under Ezra, they departed from Babylon after the Passover to return to Jerusalem, in which there was a…
