Thy children shall make haste; thy destroyers and they that made thee waste shall go forth of thee. Thy children shall make haste "They that destroyed thee shall soon become thy builders" - Auctor Vulgatae pro בניך banayich, videtur legisse בוניך bonayich, unde vertit, structores tui; cui et Septuaginta fere consentiunt, qui verterunt ῳκοδομηθης, aedificata es, prout in Plantiniana editione habetur; in Vaticana sive Romana legitur, οικοδομηθησῃ, aedificaberis. Hisce etiam Targum Jonathanis aliquatenus consentit, ubi, et aedificabunt. Confer infra Esai. Isaiah 54:13, ad quem locum rabbini quoque notarunt en tractatu Talmudico Berachot, c. ix., quod non legendum sit בניך banayich, id est. filii tui; sed בניך bonayich, aedificatores tui. Confer not. ad librum Prec. Jud. part ii., p. 226, ut et D Wagenseil Sot. p. 253, n. 9. "The author of the Vulgate appears to have read בוניך bonayich for בניך banayich, as he translates it by structures tui, 'thy builders.' The Septuagint is almost the same with the Vulgate, having ῳκοδομηθης, art built, as in the Plantin edition: but the Vatican or Roman copy reads οικοδομηθησῃ, those shalt be built. To these readings the Targum of Jonathan has some sort of correspondence, translating et aedificabunt, 'and they shall build.' See Isaiah 54:13; on which place the rabbins also remark, in the Talmudic tract Berachoth, c. 9, that we should not read בניך banayich, thy sons, but בניך bonayich, thy builders. See the note in Prae. Jud. part ii., p. 226, and also D. Wagenseil, Sot. p. 253, n. 9. "See also Breithaupt. not. ad Jarchi in loc.; and the note on this place in De Sac. Poes. Hebr. Praelect. 31. Instead of בוניך or בניך bonayich, thy builders, several MSS. read בניך baneycha, thy sons. So also the Syriac: see the above note.
Shall go forth of thee "Shall become thine offspring" - ממך יצאו mimmech yetseu, shall proceed, spring, issue, from thee, as thy children. The phrase is frequently used in this sense: see Isaiah 11:1; Micah 5:2; Nahum 1:11. The accession of the Gentiles to the Church of God is considered as an addition made to the number of the family and children of Sion: see Isaiah 49:21, Isaiah 49:22, and Isaiah 60:4. The common rendering, "shall go forth of thee, or depart from thee," is very flat, after their zeal had been expressed by "shall become thy builders:" and as the opposition is kept up in one part of the sentence, one has reason to expect it in the other, which should be parallel to it.
