A straightforward noun for the physical experience of thirst—the body's need for water. Paul lists it in 2 Corinthians 11:27 among his apostolic sufferings: hunger and thirst were part of the hardships he endured for the gospel. While Scripture also uses thirst metaphorically for spiritual longing (as Jesus does in John 4), this particular occurrence refers to literal physical deprivation. The term appears in both classical Greek and the Septuagint for the common human experience of needing to drink.
