Genesis 19:37

וַתַּשְׁקֶיןָ גַּם בַּלַּיְלָה הַהוּא אֶת־אֲבִיהֶן יָיִן וַתָּקָם הַצְּעִירָה וַתִּשְׁכַּב עִמּוֹ וְלֹֽא־יָדַע בְּשִׁכְבָהּ וּבְקֻמָֽהּ

And they made their father drink wine that night also. And the younger arose, and lay with him; and he knew not when she lay down, nor when she arose.

וַֽתַּהֲרֶיןָ שְׁתֵּי בְנֽוֹת־לוֹט מֵאֲבִיהֶֽן

Thus were both the daughters of Lot with child by their father.

וְהַצְּעִירָה גַם־הִוא יָלְדָה בֵּן וַתִּקְרָא שְׁמוֹ בֶּן־עַמִּי הוּא אֲבִי בְנֵֽי־עַמּוֹן עַד־הַיּֽוֹם

And the younger, she also bore a son, and called his name Ben-ammi—the same is the father of the children of Ammon unto this day.

וַיִּסַּע מִשָּׁם אַבְרָהָם אַרְצָה הַנֶּגֶב וַיֵּשֶׁב בֵּין־קָדֵשׁ וּבֵין שׁוּר וַיָּגָר בִּגְרָֽר

And Abraham journeyed from thence toward the land of the South, and dwelt between Kadesh and Shur; and he sojourned in Gerar.
