I took the following extract from the link ; http://www.viewzone.com/aging.html
The title was : Can science make us immortal?
“From every tree in the garden did he grant them to eat, save but one. And that tree, in the center of the garden, was called the tree of life. And the Snake said to Eve, "Eat of this fruit and you will become as God and never die.-- Genesis 3:1”
I have a doubt regarding the part labeled above, in bold and Italic. Save one, at here means, eat from all the trees except one tree.
But both of the words save and but means except. So why does except came two times in the above context?
