Genesis 26:6

וְהִרְבֵּיתִי אֶֽת־זַרְעֲךָ כְּכוֹכְבֵי הַשָּׁמַיִם וְנָתַתִּי לְזַרְעֲךָ אֵת כָּל־הָאֲרָצֹת הָאֵל וְהִתְבָּרֲכוּ בְזַרְעֲךָ כֹּל גּוֹיֵי הָאָֽרֶץ

and I will multiply thy seed as the stars of heaven, and will give unto thy seed all these lands; and by thy seed shall all the nations of the earth bless themselves;

עֵקֶב אֲשֶׁר־שָׁמַע אַבְרָהָם בְּקֹלִי וַיִּשְׁמֹר מִשְׁמַרְתִּי מִצְוֺתַי חֻקּוֹתַי וְתוֹרֹתָֽי

because that Abraham hearkened to My voice, and kept My charge, My commandments, My statutes, and My laws.’

וַֽיִּשְׁאֲלוּ אַנְשֵׁי הַמָּקוֹם לְאִשְׁתּוֹ וַיֹּאמֶר אֲחֹתִי הִוא כִּי יָרֵא לֵאמֹר אִשְׁתִּי פֶּן־יַֽהַרְגֻנִי אַנְשֵׁי הַמָּקוֹם עַל־רִבְקָה כִּֽי־טוֹבַת מַרְאֶה הִֽיא

And the men of the place asked him of his wife; and he said: ‘She is my sister’; for he feared to say: ‘My wife’; ‘lest the men of the place should kill me for Rebekah, because she is fair to look upon.’

וַיְהִי כִּי אָֽרְכוּ־לוֹ שָׁם הַיָּמִים וַיַּשְׁקֵף אֲבִימֶלֶךְ מֶלֶךְ פְּלִשְׁתִּים בְּעַד הַֽחַלּוֹן וַיַּרְא וְהִנֵּה יִצְחָק מְצַחֵק אֵת רִבְקָה אִשְׁתּֽוֹ

And it came to pass, when he had been there a long time, that Abimelech king of the Philistines looked out at a window, and saw, and, behold, Isaac was sporting with Rebekah his wife.
