It’s not in the Bible! The Bible does say Jesus was “tempted in every way, just as we are” (Hebrews 4:15) but suffering temptation might not mean the same as suffering under the curse of sin. Did Adam and Eve ever get sick in the garden before they sinned? The Bible does say that God will “wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore,” (Revelation 21:4). So that sounds like the end of sickness.
