At the Easter Mass today in the Vatican.
I was half-asleep while listening, but I think in the Holy Father's introduction to the prayers he made reference to the risen Jesus being the Bridegroom and that "we the bride of Christ" await Him with our needs...then each petition began with a quote from the Song of Solomon or the Song of Songs, including the following:
"Upon my bed at night
I sought him who my soul loves"
"I went down to the nut orchard,
to look at the blossoms of the valley."
If someone knows where the whole text of the prayers of intercession is online, please let me know.
