וַיֵּרָ֤א יְהוָה֙ אֶל־אַבְרָ֔ם וַיֹּ֕אמֶר לְזַ֨רְעֲךָ֔ אֶתֵּ֖ן אֶת־הָאָ֣רֶץ הַזֹּ֑את וַיִּ֤בֶן שָׁם֙ מִזְבֵּ֔חַ לַיהוָ֖ה הַנִּרְאֶ֥ה אֵלָֽיו׃
Yang Mahakekal menampakkan diri kepada Abram dan berfirman, “Kepada keturunanmu akan Kuberikan negeri ini.” Lalu Abram mendirikan sebuah mezbah di sana bagi Yang Mahakekal, yang telah menampakkan diri kepadanya.
