This verse is the source text of the liturgical antiphon Reges Tharsis in Christian Cathedral music. In this Psalm, the 'chain of scaled correlates' consisting of 'mountains and hills', 'rain and showers', 'seas and river' leads up to the phrase 'Tarshish and islands', indicating that Tarshish was a large island.[2] Isaiah contains three prophecies mentioning Tarshish. First 2:16 "against all the ships of Tarshish, and against all the beautiful craft," then Tarshish is mentioned at length in Chapter 23 against Tyre.
