'Athirst' in the Bible

Then shall the righteous answer him, saying, Lord, when saw we thee hungry, and fed thee? or athirst, and gave thee drink?

Then shall they also answer, saying, Lord, when saw we thee hungry, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee?

And he said unto me, They are come to pass. I am the Alpha and the Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.

And the Spirit and the bride say, Come. And he that heareth, let him say, Come. And he that is athirst, let him come: he that will, let him take the water of life freely.
