Jeremiah 31:35

"If laws of day and night cease to speak before my face, says the Lord, then the descendants of Israel cease to be a nation forever." It is impossible that the world order established from the beginning would change, that is, movement of stars, change of seasons. Therefore, without doubt, the promise given to David would not be left unfulfilled, and his kingdom and his seed would not cease before God's face. Although this prophecy was fulfilled in its own time for Zerubbabel, who ruled over David's kingdom, it was more completely fulfilled in our Lord, as even the angel said, "The Lord God will give him the throne of his father David. He will reign in the house of Jacob forever, and his kingdom will have no end."And the prophet repeats and confirms later on what is said here about the spread and eternity of Christ's kingdom by saying, "Just as the heavenly stars could not be counted and the sands of the sea could not be measured, so I will increase the seed of David," that is, the seed of his Word (Logos), son of David, priests and the Levites of the new covenant. According to their dignified status, the prophet depicts the gospel and the church of Christ in the image of the powers of heaven (stars) and their spread in the image of the sands of the sea, because thus it should be that the gospel and the church would become known to all the ends of the universe and that all nations would believe in them.

(Verse 35, 36) Thus says the Lord, who gives the sun for light by day, the order of the moon and the stars for light by night, who stirs up the sea so that its waves roar: The Lord of hosts is his name. If these laws (or statutes) depart from before me, says the Lord, then the seed of Israel shall also cease from being a nation before me forever. And in the beginning of Genesis, we read that the sun was placed in the sky for light by day, and the moon and stars for light by night (Gen. 1). And in the psalm it says: Day to day pours out speech, and night to night reveals knowledge (Psalm 19:2), meaning that night and day succeed each other. Just as, he says, the order of things, especially the celestial spheres, cannot be changed, and the waves of the sounding sea roll toward the shore, and the terrifying noise of the swelling waves is heard, but it cannot go beyond what is commanded by God, according to that: You set a boundary that they may not pass, so that they might not again cover the earth (Psalm 104:9). Similarly, he says, the offspring and lineage of Israel will be perpetual by the will of the Lord, and will never fail. However, here the laws are not to be understood as Mosaic, but as the constitution and order of nature. Let us ask the Jews, if the heavens will perish, and all will become old like a garment; and to the Lord it is said: But thou art the same, and thy years shall not fail (Ps. CI, 28), how can the seed of Israel be perpetual? For if the heavens perish, the seed of Israel will perish; but if it is perpetual, then the heavens will not perish. But if the Scriptures cannot lie, and the heavens are perishable, then the seed of Israel will perish as well, especially since Jacob speaks to his sons, saying: Come, and I will tell you what will happen in the last days (Gen. XLIX, 1). When it is said, in the last days, therefore the world will cease to exist, and there will be a different arrangement of things (or dispensation). This is against them. Furthermore, the Gospel also shows that this world is not everlasting, saying: Heaven and earth will pass away (Matth. XXIV, 35). And behold, I am with you all days, even to the consummation of the world (Matt. XXVIII, 20). Let us also say it differently: As long as this world exists, the seed of Israel and the Jewish nation will remain, not in those who are now unbelievers, but in those who…
