Komentaryo sa Genesis 30:8: Rashi, Rashbam, Radak & Sforno

נפתולי אלהים WRESTLINGS OF GOD — Menachem ben Seruk explains in his Machbereth (Dictionary) that the word נפתולי is of the same root as פתיל in (Numbers 19:15) “a covering (פתיל) closely bound upon it”, so that the words here mean: By bonds from God have I been joined to my sister (made equal to her) to merit the privilege of having children. I, however, explain it in the same sense as (Deuteronomy 32:5) “perverse and crooked (עקש ופתלתול)”. I have been persistent and have made many importunities and wrestlings with God that I may become like my sister.

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,

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.

גם יכלתי AND I HAVE PREVAILED — He has yielded to my importunities. Onkelos translated it in the sense of prayer (תפלה), in this way: נפתולי אלהים נפתלתי means prayers that were pleasing to God I offered and I was accepted and was answered like my sister.
