Definition: The profane word you're referring to is "Lamentations 1:10," which was famously used by Pope John XXIII during his 1963 pontificate. This verse, from the first part of Psalm 102 in the Hebrew Bible, is a cry for help and despair over human sin.
An example sentence using this verse might be, "In the depths of my despair I see no light." This phrase could symbolize Pope John's deep sadness at his own fallibility and the suffering of others.
