19 And these are the generations of Isaac, Abraham’s son: Abraham begat Isaac: 21 And Isaac entreated the Lord for his wife, because she was barren: and the Lord was entreated of him, and Rebekah his wife conceived. 22 And the children struggled together within her; and she said, If it be so, why am I thus? And she went to inquire of the Lord. 23 And the Lord said unto her, Two nations are in thy womb, and two manner of people shall be separated from thy bowels; and the one people shall be stronger than the other people; and the elder shall serve the younger.
Isaac’s story only begins in earnest after Abraham has passed away. I have mentioned before that some people, such as Abraham, seem to have a story so expansive that it is necessary to get out from under their umbrella before one’s own narrative begins. Up until this moment the only word or action we heard from Isaac was when he walked through the field to meet Rebekah for the first time. Here, though, we learn that he, like his father, had a special relationship with God. Rebekah was unable to bear children, so Isaac spoke to the Lord for her sake, and God healed her.
That exchange sounds very simple. Evidently God was more than ready to heal Rebekah, but perhaps He waited for Isaac’s petition to start cultivating that God-Son relationship with him. Admittedly the relationship between God and Isaac is only briefly touched on in the Bible, not nearly so much as it was detailed with Abraham, his father, or as it will be with Jacob, his son.
However, we do get some special insights into God’s relationship with Rebekah. In these verses we read how she felt her twin children struggling in her womb, and went to inquire of the Lord why it was so. This already shows her quality of faith, believing that she could receive understanding for the simple matters of life. And indeed, she did. Long before the drama would play out between Esau and Jacob, Rebekah already knew from God what would happen and who would prevail over the other. Later on, when she helped Jacob to secure his father’s blessing, she was only helping him into the larger story that she already knew God intended for him.
