In case you didn't know remember this Noah and Shem was still alive when Abraham was born.He would have learnt a lot from them about God.In fact Shem outlived Abraham by 33 years.Abraham would have passed down that knowledge to Isaac and so on.
Nupay kasta, makapakigtot ti sungbat ni Jesus: “No annaknakayo ni Abraham, aramidenyo met koma dagiti inaramidna.”
