The term Ben Porat Yosef is taken from Jacob’s blessing on his deathbed to his son Joseph. Before Jacob passed away he bestowed his blessing upon Joseph - it’s an ancient blessing for abundance, fertility, protection, and strength. The Hebrew original words are “BEN PORAT YOSEF, BEN PORAT ALEY AIN, BANOT, ZAADA ALEY SHOR”. “BEN PORAT” means - a son of a fruitful tree, which is a symbol of abundance and fertility. “ALEY AIN” the tree is depicted as standing near a spring or a fountain - again a symbol of longevity and abundance. ”BANOT ZAADA ALEY SHOR” the tree’s branches are curved or becoming entangled on a wall - a symbol of strength and protection. The BEN PORAT blessing is also considered a powerful protection against Evil Eye since Joseph was protected and blessed against the people’s envy.
Genesis 49:22 “Joseph is a fruitful vine, a fruitful vine by a fountain; its branches run over the wall."
