They shall not labour in vain, nor bring forth for trouble; for they are the seed of the blessed of the LORD, and their offspring with them. They shall not labor in vain "My chosen shall not labor in vain" - I remove בחירי bechirai, my elect, from the end of the twenty-second to the beginning of the twenty-third verse, on the authority of the Septuagint, Syriac, and Vulgate, and a MS.; contrary to the division in the Masoretic text. - L. The Septuagint is beautiful: My chosen shall not labor in vain, neither shall they beget children for the curse; for the seed is blessed of the Lord, and their posterity with them."
Nor bring forth for trouble "Neither shall they generate a short-lived race" - לבהלה labbehalah, in festinationem, "what shall soon hasten away." Εις καταραν for a curse, Sept. They seem to have read לאלה lealah. - Grotius. But Psalms 78:33 both justifies and explains the word here: -
ימיהם בהבל ויכל yemeyhem bahebel vayechal בבהלה ושנותם babbehalah ushenotham
"And he consumed their days in vanity;
And their years in haste."
μετα σπουδης, say the Septuagint. Jerome on this place of Isaiah explains it to the same purpose: "εις ανυπαρξιαν, hoc est, ut esse desistant."
