Interesting that the title is taken word for word from Thomas Cahill’s book about the Holy Land just before, during, and after the life of Christ.
It’s taken from Genesis 49:26
Douay-Rheims Bible
The blessings of thy father are strengthened with the blessings of his fathers: until the desire of the everlasting hills should come; may they be upon the head of Joseph, and upon the crown of the Nazarite among his brethren.
