And Isaac was comforted for his mother.
Joel 2:16 - The First "Chuppah"
"Gather the people, Sanctify the congregation, Assemble the elders, Gather the children, And those suckling infants; Let the bridegroom go forth from his chamber (chedro), And the bride out of her pavilion (chuppah-tah)."
(5)Their line is gone out through all the earth, and their words to the end of the world. In them hath Adonai set a tent for the sun, (6) Which is as a bridegroom coming out of his chamber (chuppah-to), and rejoices as a strong man to run his course.
