So [Catholic] Biden in recalling [the bride's] wedding misquote the lyrics from the hymn that is based on [Psalm 91] with the quote from [Psalm 118] that is what Hava Nagila is based on.

• union of bride and groom

• union of Christian and Jew

• union of Christ and the Church(bride according to some)

• union of Psalm 91 and Psalm 118
