psuchros describes a cool-temperature cup of water and, in Revelation, the “cold” alternative contrasted with being lukewarm.

Most occurrences place the term in Revelation’s contrast between hot, cold, and lukewarm conditions when works are addressed; Matthew 10:42 uses it for the temperature of water given to drink.

1. The cold alternative to hot and lukewarm · dominant

   In Revelation 3:15, the nominative masculine form occurs in the statement about works that are neither “cold nor hot”; in Revelation 3:16, the same nominative masculine form stands again in the contrast with being “lukewarm.” The APB renders both clauses with “cold,”.

   In Matthew 10:42, the genitive singular neuter form qualifies the water in a cup given to one of the little ones to drink. The APB renders the phrase “a cup of cold water,”.

   Matthew 10:42

In the Anselm Project Bible: The APB uses “cold” for the water in Matthew 10:42 and for the repeated contrast with “hot” and “lukewarm” in Revelation 3:15 and Revelation 3:16. These are verse-level renderings rather than word-by-word alignments.
