Psalm 45 is the 45th psalm of the Book of Psalms. In the Greek Septuagint version of the bible, and in its Latin translation in the Vulgate, this psalm is Psalm 44 in a slightly different numbering system. In Latin, it is known as "Eructavit cor meum".[1] It was composed by the sons of Korach on (or "according to") the shoshanim–either a musical instrument or the tune to which the psalm should be sung. The psalm has been interpreted as an epithalamium, or wedding song, written to a king on the day of his marriage to a foreign woman, and is one of the royal psalms.
