Isaiah 65:20 - Exposition

There shall be no more thence an infant of days; i.e. there shall not go from the new Jerusalem into the unseen world any infant of a few days old. On the contrary, even "the youth" shall reach a hundred; i.e. one who dies when he is a hundred shall be regarded as cut off in his youth. The general rule shall be, that old men shall "fill their days," or attain to patriarchal longevity. Even the sinner, who is under the curse of God, shall not be cut off till he is a hundred. What is most remarkable in the description is that death and sin are represented as still continuing. Death was spoken of as "swallowed up in victory" in one of the earlier descriptions of Messiah's kingdom ( Isaiah 25:8 ).
