'Left' in the Bible

Wherefore when we could no longer forbear, we thought it good to be left at Athens alone;

For this we say unto you by the word of the Lord, that we that are alive, that are left unto the coming of the Lord, shall in no wise precede them that are fallen asleep.

then we that are alive, that are left, shall together with them be caught up in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
