Isaiah 39:7-8

7Some of your own descendants will also go to Babylon. Soldiers from Babylon will take them away from here. Your descendants will become eunuchs in the king of Babylon's palace.” That is what the Lord says. ’

8Hezekiah said to Isaiah, ‘The Lord's message that you have spoken to me is good.’ But he was thinking, ‘While I am still alive, people will live safely without any trouble.’
