Esias 65:23

23 My chosen shall not toil in vain, neither shall they beget children to be cursed; for they are a seed blessed of God, and their offspring with them.

Esias 65:23 In-Context

21 and they shall build houses, and themselves shall dwell in ; and they shall plant vineyards, and themselves shall eat the fruit thereof.
22 They shall by no means build, and others inhabit; and they shall by no means plant, and others eat: for as the days of the tree of life shall be the days of my people, they shall long enjoy the fruits of their labours.
23 My chosen shall not toil in vain, neither shall they beget children to be cursed; for they are a seed blessed of God, and their offspring with them.
24 And it shall come to pass, before they call, I will hearken to them; while they are yet speaking, I will say, What is it?
25 Then wolves and lambs shall feed together, and the lion shall eat chaff like the ox, and the serpent earth as bread. They shall not injure nor destroy in my holy mountain, saith the Lord.
