Rebekah was "a rose between thorns." Her father was the Aramean Bethuel, and her brother was Laban, but she did not walk in their ways. Her piety was equal to Isaac's. Nevertheless their marriage was not entirely happy, for they lived together no less than twenty years without begetting children.
Rebekah besought her husband to entreat God for the gift of children, as his father Abraham had done. At first Isaac would not do her bidding. God had promised Abraham a numerous progeny, and he thought their childlessness was probably Rebekah's fault, and it was her duty to supplicate God, and not his. But Rebekah would not desist, and husband and wife repaired to Mount Moriah together to pray to God there.
And Isaac said: "O Lord God of heaven and earth, whose goodness and mercies fill the earth, Thou who didst take my father from his father's house and from his birthplace, and didst bring him unto this land, and didst say unto him, To thee and thy seed will I give the land, and didst promise him and declare unto him, I will multiply thy seed as the stars of heaven and as the sand of the sea, now may Thy words be verified which Thou didst speak unto my father.
For Thou art the Lord our God, our eyes are toward Thee, to give us seed of men as Thou didst promise us, for Thou art the Lord our God, and our eyes are upon Thee." Isaac prayed furthermore that all children destined for him might be born unto him from this pious wife of his, and Rebekah made the same petition regarding her husband Isaac and the children destined for her.
