Genesis 30:10

וַתֹּאמֶר רָחֵל נַפְתּוּלֵי אֱלֹהִים נִפְתַּלְתִּי עִם־אֲחֹתִי גַּם־יָכֹלְתִּי וַתִּקְרָא שְׁמוֹ נַפְתָּלִֽי

And Rachel said: ‘With mighty wrestlings have I wrestled with my sister, and have prevailed.’ And she called his name Naphtali.

וַתֵּרֶא לֵאָה כִּי עָמְדָה מִלֶּדֶת וַתִּקַּח אֶת־זִלְפָּה שִׁפְחָתָהּ וַתִּתֵּן אֹתָהּ לְיַעֲקֹב לְאִשָּֽׁה

When Leah saw that she had left off bearing, she took Zilpah her handmaid, and gave her to Jacob to wife.

וַתֹּאמֶר לֵאָה בגד וַתִּקְרָא אֶת־שְׁמוֹ גָּֽד

And Leah said: ‘Fortune is come! ’ And she called his name Gad.

וַתֵּלֶד זִלְפָּה שִׁפְחַת לֵאָה בֵּן שֵׁנִי לְיַעֲקֹֽב

And Zilpah Leah’s handmaid bore Jacob a second son.
