I found verses 70 thru 75 of the second text very interesting regarding the ram. (Lots of room for discussion there if anyone chooses to do so.)_______
Also, I think probably the only real unconditional love that exists in the world is between a mother and her child. The account described in the book of Jasher describes Sarah's love for Isaac in much more detail than the biblical account does. Most of us mothers can relate to the Jasher account totally:
Sarah is beside herself with worry and concern over Isaac going off on this journey with Abraham. The description of this heartache is palpable. She agonizes over this trip, admonishing Abraham to look after him carefully, to stay near him, to not let him wander off alone, etc. She tells Abraham that Isaac's soul is bound to hers.
Then she stays up all night hugging Isaac, instructing him, kissing him, and preparing him for the trip. She dresses him in the finest and makes sure he has all the provisions he will need, even though he is a grown man. She cries before he leaves, cries while she waves good-bye to him, and cries while he is gone. Perhaps she intuitively knows that something is not right. Abraham has not told her the real reason he's taking Isaac on this journey. When they don't come home as soon as she thinks they should have, she goes off looking for him. The description of her pain and worry is heart-breaking. Satan disguises himself and tells her Isaac has been sacrificed, then he disguises himself again and tells her he's alive. She is so overcome with joy at the last news, that she dies (probably from a stroke or heart attack).
In the end, it is this Mother that suffers the most from the worry and stress and love for her child, and it is the Mother that loses her life.
