For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, Matthew 25:42
Gill's Exposition
I was thirsty, and ye gave me no drink; as not the least morsel of bread to eat, so not so much as a cup of cold water to drink; which with what follows, are manifest tokens and evidences, that they did not belong to Christ, were not true believers in him, nor had they any real love to him: the grace of God was not in them, and therefore had neither right unto, nor meetness for, the kingdom of heaven; but were righteously banished from the presence of the Lord, and sent to dwell among everlasting burnings; for righteous it was, that such as they who would not show any love to him here, should not dwell with him for ever hereafter.
