They were immortal until that time.

在此之前他们可以长生不老
So, we see in Genesis the embodiment of this idea

所以在《创世纪》中我们可以看到
that diseases are a punishment of sin.

疾病作为罪之罚这一观点的体现
This was also clear--you can read further in the Bible,

再往下读还有相似情节
in the book of Exodus,

第二卷《出埃及记》
where you learn about the bondage of the Israelites in Egypt

写道以色列人在埃及的奴隶生涯
and God asking for Moses and Aaron

上帝派摩西和亚伦去见法老
for the Pharaoh to release his chosen people.

请求他释放选中的以色列人
But the Pharaoh's heart was hardened

然而法老铁石心肠
and so the Egyptians were punished with this series of terrible plagues

于是埃及人遭受一系列可怕瘟疫的惩罚
that are all in Exodus.

这在《出埃及记》中反复提及
Another way of embodiment of this was in Psalm 91,

在《诗篇》第九十一章中另有体现
