Genesis 30:8

And Rahel said, With affliction afflicted was I before the Lord in prayer; therefore He hath received my request that I might have a son as my sister, and hath given me two. Even so are my children to be redeemed from the hand of their enemies when they shall afflict themselves in prayer before the Lord; and she called his name Naphtali.

נפתולי אלוקים נפתלתי, this formulation is partly due to literary considerations, so that the letter נ at the beginning of the word נפתולי is due primarily in order to match the latter נ in the word נפתלתי. We encounter something similar is the construction of Samuel I 20,28 נשאל נשאל דוד,

נפתלי אלוהים נפתלתי, the word נפתולי is a variant of the word פתיל as in צמיד פתיל, a tightly fitted lid (Numbers 19,15) Rachel meant that her cleaving to her husband was an attachment containing spiritual, religious dimensions, making the bond between them immeasurably stronger.

עם אחותי, I did this jointly with my sister, both of us having liberated our respective handmaids in order to enable them to become mothers of the founding fathers of the Jewish people. This is what they meant when considering the sons of these former handmaids as בנים instead of as עבדים. Accordingly, Leah had already liberated her handmaid Zilpah before Bilhah had given birth to Naftali. How else could 8 of the 12 tribes have been born within 7 years of Yaakov’s getting married? 6 of these sons were Leah’s and 2 were Zilpah’s. Assuming each pregnancy lasted 9 months, and further assuming that none of these pregnancies occurred simultaneously, 8 times 9 months amounts to 72 months, i.e. 6 years. Unless Leah had given her handmaid to Yaakov before Naftali was born there would not have been enough time for Joseph to have been born at the end of the second 7 years of Yaakov’s service. At that time, after Joseph’s birth, Yaakov requested permission to go home to his parents.(3,26). The only alternative to our calculation would be that all the children were born after only 7 months pregnancy, and that none of the mothers observed even basic days of ritual impurity before again sleeping with their husbands.

גם יכולתי, I have achieved what I had planned by giving my maidservant to Yaakov.

ותהר...ותאמר נפתולי אלוקים, “I have engaged in a difficult contest with my sister;” the root פתל means to twist or be twisted as in פתיל תכלת, a string made of blue wool, i.e. two strands of yarn combined to make a cord, twisted. By pulling the two strands together the whole string becomes stronger. ותהר...ותאמר נפתולי אלוקים, “I have engaged in a difficult contest with my sister;” the root פתל means to twist or be twisted as in פתיל תכלת, a string made of blue wool, i.e. two strands of yarn combined to make a cord, twisted. By pulling the two strands together the whole string becomes stronger.

אלוהים. The use of the word אלוהים is symbolic of the fierceness of the sisters’ competition, When we want to emphasise something as being extraordinary, we sometimes use the word “elohim” to do this, as for instance in the description of the size of the city of Nineveh in Jonah 3,3 where it is described as עיר גדולה לאלוהים. A similar expression in Psalms 36,7 כהררי א-ל describes towering mountains by using the word elohim as the appropriate adjective to describe this. Psalms 80,11 Jeremiah 2,31, and Song of Songs 8,6 are some more examples of the use of the word el or elohim as such an adjective.

נפתולי אלוקים נפתלתי עם אחותי, “I have wrestled mightily with my sister;” Rachel meant that she had managed to put up with a great deal of pain in her struggle with her sister but had managed thus far to hold her own. An alternate explanation: the expression נפתל is similar its meaning to the line in Deuteronomy 32, ,5: דור עקש ופתלתול, “a crooked and perverse generation.” She had to behave in a perverse manner through making allowance for her sister’s fertility. Nonetheless, she felt that she had prevailed seeing that she now had also two children to her credit. A third approach to this statement by Rachel: the word is related to the word פתיל as in צמיד פתיל in Numbers 19,15, where it means “a close connection,” She hinted that whereas Betzalel, the chief artisan that would build the Tabernacle in the future of whom the Torah stated that he was endowed with a great deal of wisdom, (Exodus 31,3) would be descended from Leah, her sister, at least his chief assistant Oholiov, would be descended from the tribe of Dan, one of her descendants through Bilhah. (Exodus 31,6) She would enjoy the vicarious satisfaction of having a share in that undertaking. She would also prevail, יכולתי, when it would come to the building of Solomon’s Temple when Chirom from the tribe of Naftali helped Solomon greatly. (Kings I, 7,14).
