<p>1:11 <em>They shall perish, but You continue; and they all shall wear out as does a garment</em>- As noted on :10, the purpose of the quotation is to demonstrate the Lord's superiority over Angels. One approach is to understand the Hebraic way of stating that 'even X shall happen to prove the greatness of Y'; e.g. heaven could pass away X but the Lord's words would not Y (Mt. 24:35). This is not to say that X shall literally happen; it is stated as a hyperbole, to demonstrate the greatness of Y. And that may be the case here too. God's eternity is contrasted with the relative passing of the Heavens, which were made by Angels. &quot;They shall perish&quot; may not therefore mean they shall literally perish.</p><p>The context of Ps. 102 is however pertinent. The &quot;set time had come&quot; suggests that the Psalmist is writing maybe in captivity in Babylon as the predicted 70 years of Judah&rsquo;s captivity there came to a close, and he looks forward to the promised restoration and rebuilding of Jerusalem. He enthuses in :16 that &quot;Yahweh has built up Zion&quot;- although He had not then done so (:13). The earlier part of the Psalm laments this. But the Psalmist believed in God&rsquo;s prophecies of doing so, and considered them as good as already fulfilled. Faith is all about adopting God&rsquo;s perspective, seeing future promises as if they have already been fulfilled, thereby enabling us to live the Kingdom life now in its essence. Then in Ps. 102:25 we read of how &quot;Of old, You laid the foundation of the earth, the heavens are the work of Your hands&quot;. The language of laying foundations is nearly always used about the laying of the foundations of the new, rebuilt temple at the time of return from exile (Ezra 3:10-12; 5:16; Is. 44:28; Hag. 2:18; Zech. 4:9; 8:9); and this is the context of this Psalm (see on :13 and :16). The &lsquo;heavens and earth&rsquo; refer to Israel (Is. 1:2) and the temple. Although they had &lsquo;perished&rsquo; in the Babylonian invasion and destruction of the first temple, God remained and would, the Psalmist believed, install a new temple system (as outlined in Ez. 40-48). However, this never quite happened as God intended due to Judah&rsquo;s weakness, and so these prophecies were reapplied to how the entire Jewish system based around the temple and Law of Moses would &lsquo;perish&rsquo; and God&rsquo;s new temple system based around the exalted Lord Jesus would come into existence (Heb. 1:10 and context).</p>
