Isa 54:2

“Here is the spiritual sense. Anyone who is in a tent does not have a secure and everlasting dwelling but is always changing places and hurrying on to the next.… For the end of "living in tents" is the taking possession of the eternal home, whose foundations do not shift nor are moved around. Those planted in the house of God, in his very atrium, flower so that from the blooms they may come to bear fruit and be able to say, "I am like an olive tree bearing fruit in God's house."”

“(Vers. 2, 3.) Dilata locum tentorii tui, et pelles tabernaculorum tuorum extende: ne parcas: longos fac funiculos tuos, et clavos tuos consolida. Ad dexteram enim et ad laevam penetrabis, et semen tuum gentes haereditabit, et civitates desertas inhabitabit. LXX: Dilata locum tabernaculi tui, et pelles aulaeorum tuorum fige, ne parcas. Protende funiculos, et clavos tuos conforta adhuc in dextris, et in sinistris dilata, et semen tuum possidebit gentes, et civitates desertas habitare facies. To whom he had said: Praise, O barren one, who does not bear; break the bonds by which you were previously bound, and shout in confession of the Lord, whom you did not have children with, now you are commanded the same as the likeness of the tent of Moses, which he once had (Exodus 36) in the desert, to expand his tent and stretch out his skins; and make longer cords and fix nails, with which the entire tent is formed, so that it may be firmly set and strengthened, lest it be dispersed by the blasts of the wind. And it should extend to both the right and the left, and by no means should it imitate the narrowness of the Jewish tabernacle, which measured one hundred cubits in length and fifty in width, nor should it be constrained by the brevity of the Temple, which had sixty cubits in length and twenty in width. But it should continue to have space on the right and on the left. (Exodus 27). And so that we may not think this can be said in vain concerning the frivolous contention of the Hebrews about Zion, which is to be restored to its ancient state by the Lord, he explains more clearly what was hidden: And your offspring shall inherit the nations. About which we also read in the Gospel: 'He went out who sows to sow' (Matthew XIII, 3); and again: 'Did you not sow good seed in your field?' (Ibid., 27)? This seed will also make deserted cities be inhabited, so that Churches of the nations may rise in the whole world. Or surely the seed must be said to be the Apostles, and the remnants of the Jewish people. About which in this same Prophet it is said: 'Unless the Lord of hosts had left us seed, we would have been like Sodom, and similar to Gomorrah' (Isaiah I, 9). And the Apostle says: 'The remnants were saved' (Rom. II, 5). This refers to the greatness of the Churches, which, starting from one place in Judea and that too very narrow, will extend their boundaries to the whole world. Let us come to spiritual understanding. He who is in a tabernacle does not possess a firm and permanent dwelling; but he always changes places and hastens to go further, saying in the psalm: 'I will pass to the place of the wonderful tabernacle' (Ps. XLI, 5), forgetting the things that are past and extending himself into the future, until he reaches the reward of the heavenly calling. We read about this tabernacle and in another place: How lovely are your dwelling places, O LORD of hosts! My soul longs, yes, even faints for the courts of the LORD (Psalm 84:1). And it continues: Blessed are those who dwell in your house; they will praise you forever and ever (Ibid., 6). For the end of the tabernacles is the possession of the eternal house, which does not change its foundations, nor is it moved from one place to another. For those who are planted in the house of the LORD, they will flourish in the courts of our God, that they may go from flowers to fruit, and may say: But I am like a fruitful olive tree in the house of God (Psalm 52:10). Finally, the holy man, hastening to pass by the tabernacles and desiring to see the house of God, says that he has one wish, that he never leaves the house of God: One thing I have asked of the Lord, this I will seek: that I may dwell in the house of the Lord all the days of my life (Ps. 26:1). Therefore, the tabernacle must be enlarged, and curtains and skins must be stretched, and ropes of various and diverse discourses must be extended further, and nails must be firmly fixed on the right and left, so that the seed of the word, that is, the teaching of God, may be able to possess the nations; and to make habitable cities, which he received who doubled the mina. However, the right hand and the left hand in the Holy Scriptures are then interpreted in a good sense, when we understand them both according to the spirit and according to the letter through the weapons of righteousness on the right and on the left (2 Corinthians VI), so that we may embrace the more humble understanding of life's instruction and the examples of our elders, and be transferred from the present to the future in a spiritual and sublime manner. This is what the Lord was speaking to the Pharisees when they asked Him: 'Render to Caesar the things that are Caesar's, and to God the things that are God's' (Matthew XXII, 21), so that we may be subject to the powers of this world, which rightly hold the sword for the punishment of those who do evil, which is understood as the left hand; and let us render to God the things that are God's, so that we may fear no other, except Him who has power over both soul and body, which is understood as the right hand (Matthew X). Finally, it is said about the wisdom of God, to which nothing precious can be compared, that it has length of life and many years in its right hand; and in its left hand, riches and glory, so that those riches are understood which exist in present knowledge and good works, and the glory which the one who receives it, through whose works God is glorified among the nations, but the length of life and many years signify eternal life, which, neglecting the present, hastens to the future.”

“Enlarge the place of thy tent, because of the larger number of thy children. יטו Let them stretch forth. Let the children of the desolate stretch forth, or let people stretch forth; comp. ויאמר and one said (Gen. 48:1). אל תחשכי Prevent not, the people from stretching forth the curtains of thy tent. Thy cords. The cords of thy tent.—The restoration of the towns and villages is meant by this figure.”

“978. Second, he exhorts them to enlarge their place under the metaphor of a tent: enlarge the place, as to the ground over which the tent is extended; and stretch out the skins, with which it is covered; lengthen your cords, with which the stakes are tied; and strengthen your nails, with which the boards are joined, or the stakes themselves. And we read that these things were in the tabernacle of the covenant (Exod 26 and 36). Because of this great multitude of men it is necessary to seek a dwelling larger than the promised land, above: the children of your barrenness shall still say in your ears: the place is too strait for me, make me room to dwell in (Isa 49:20). 984. Note also on the words: enlarge the place of your tent (Isa 54:2), that the heart is to be enlarged first, because of the greatness of its guest: do not I fill heaven and earth, says the Lord? (Jer 23:24); second, because of the multitude of his gifts, below: then shall you see, and abound, and your heart shall be enlarged (Isa 60:5); third, because of the completion of the way: I have run the way of your commandments, when you didst enlarge my heart (Ps 118[119]:32).”
