parusia of Jahve re-echoes here in a lyric form. כּי, Psa 102:17, states the ground of the reverence, just as Psa 102:20 the ground of the praise. The people of the Exile are called in Psa 102:18 הערער, from ערר, to be naked: homeless, powerless, honourless, and in the eyes of men, prospectless. The lxx renders this word in Jer 17:6 ἀγριομυρίκη, and its plural, formed by an internal change of vowel, ערוער, in Jer 48:6 ὄνος ἄγριος, which are only particularizations of the primary notion of that which is stark naked, neglected, wild. Psa 102:18 is an echo off Psa 22:25. In the mirror of this and of other Psalms written in times of affliction the Israel of the Exile saw itself reflected.
Verses 18-22
The poet goes on advancing motives to Jahve for the fulfilment of his desire, by holding up to Him what will take place when He shall have restored Zion. The evangel of God's redemptive deed will be written down for succeeding generations, and a new, created people, i.e., a people coming into existence, the church of the future, shall praise God the Redeemer for it. דּור אחרון as in Psa 48:14; Psa 78:4. עם נברא like עם נולד Ps 22:32, perhaps with reference to deutero-Isaianic passages like Isa 43:17. On Psa 102:20, cf. Isa 63:15; in Psa 102:21 (cf. Isa 42:7; Isa 61:1) the deutero-Isaianic colouring is very evident. And Psa 102:21 rests still more verbally upon Psa 79:11. The people of the Exile are as it were in prison and chains (אסיר), and are advancing towards their destruction (בּני תמוּתה), if God does not interpose. Those who have returned home are the subject to לספּר. בּ in Psa 102:23 introduces that which takes place simultaneously: with the release of Israel from servitude is united the conversion of the world. נקבּץ occurs in the same connection as in Isa 60:4. After having thus revelled in the glory of the time of redemption the poet comes back to himself and gives form to his prayer on his own behalf.
Verses 23-28
On the way (ב as in Psa 110:7) - not “by means of the way” (ב as in Psa 105:18), in connection with which one would expect of find some attributive minuter definition of the way - God hath bowed down his strength (cf. Deu 8:2); it was therefore a troublous, toilsome way which he has been led, together with his people. He has shortened his days, so that he only drags on wearily, and has only a short distance still before him before he is entirely overcome. The Chethîb כחו (lxx ἰσχύος αὐτοῦ)
