Genesis 30:8

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. 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. נפתלתי means my prayer was accepted. There are many Midrashic explanations in the manner of Notaricon (i.e. making the letters of the word the initial letters of phrases having reference to the matter in question) (Genesis Rabbah 71:8).

And Raĥel said, With great wrestlings have I wrestled with my sister, and I have prevailed: and she called his name Naftali.
