'Hungering' 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?
