When Isaac grew up to be a faithful servant of God, his name no doubt continued to bring a smile to the faces of Abraham and Sarah as they enjoyed the company of this beloved son. ​ — Genesis 17: 17, 19; 18: 12, 15; 21: 6.
Kui armastatud pojast Iisakist oli sirgunud ustav jumalateenija, tõi ta nimi kahtlemata Aabrahami ja Saara näole naeratuse ajal, mil ta koos nendega oli.
