“Whoever gives

Even a cup of cold water

To one of these little ones,

In the name of a disciple,

Truly,

I say to you,

None of these

Will lose their reward.”

 

καὶ ὃς ἐὰν ποτίσῃ ἕνα τῶν μικρῶν τούτων ποτήριον ψυχροῦ μόνον εἰς ὄνομα μαθητοῦ, ἀμὴν λέγω ὑμῖν, οὐ μὴ ἀπολέσῃ τὸν μισθὸν αὐτοῦ.

 

This verse of Matthew is similar to Mark, chapter 9:41.  Jesus said that whoever gave a cup of cold water to drink to these small or little ones (καὶ ὃς ἐὰν ποτίσῃ ἕνα τῶν μικρῶν τούτων ποτήριον ψυχροῦ), if only in the name of his disciples (μόνον εἰς ὄνομα μαθητοῦ,), they would not lose their reward (οὐ μὴ ἀπολέσῃ τὸν μισθὸν αὐτοῦ).  Once again, Jesus spoke with authority (ἀμὴν λέγω ὑμῖν).  They would not lose anything by giving this small gesture of cold water to his disciples or the little ones or the less important in society.  These least important in society might be his disciples themselves.
