'Thirsting' in the Bible

Happy those hungering and thirsting for righteousness -- because they shall be filled.

'Then shall the righteous answer him, saying, Lord, when did we see thee hungering, and we nourished? or thirsting, and we gave to drink?

'Then shall they answer, they also, saying, Lord, when did we see thee hungering, or thirsting, or a stranger, or naked, or infirm, or in prison, and we did not minister to thee?

and He said to me, 'It hath been done! I am the Alpha and the Omega, the Beginning and the End; I, to him who is thirsting, will give of the fountain of the water of the life freely;

And the Spirit and the Bride say, Come; and he who is hearing -- let him say, Come; and he who is thirsting -- let him come; and he who is willing -- let him take the water of life freely.
