When a person never waivers from the purity of the land, the purity of the land never waivers from the person.
The first person to be born Jewish, Isaac was purity personified, never leaving the land of Israel, then called Canaan. Isaac resembled his father Abraham. The binding of Isaac occurred when he was 37. At 40, Isaac married Rebecca. 20 years later they had twins, Jacob and Esau. In his later years, Isaac’s eyesight would weaken, one of the reasons given is so that Isaac would not see Esau’s destructive ways. Living in Hebron at the age of 180 Isaac passed away and was laid to rest in the Double Cave, along with his parents and wife.
