'Lose' in the Bible

He that findeth his life shall lose it; and he that loseth his life for my sake shall find it.

And whosoever shall give to drink unto one of these little ones a cup of cold water only, in the name of a disciple, verily I say unto you he shall in no wise lose his reward.

For whosoever would save his life shall lose it: and whosoever shall lose his life for my sake shall find it.
