Genesis 35:7

וַיִּ֤בֶן שָׁם֙ מִזְבֵּ֔חַ וַיִּקְרָא֙ לַמָּק֔וֹם אֵ֖ל בֵּֽית־אֵ֑ל כִּ֣י שָׁ֗ם נִגְל֤וּ אֵלָיו֙ הָֽאֱלֹהִ֔ים בְּבָרְח֖וֹ מִפְּנֵ֥י אָחִֽיו׃

καὶ ᾠκοδόμησεν ἐκεῖ θυσιαστήριον, καὶ ἐκάλεσεν τὸ ὄνομα τοῦ τόπου ἐκεῖ γὰρ ἐπεφάνη αὐτῷ ὁ θεὸς ἐν τῷ ἀποδιδράσκειν αὐτὸν ἀπὸ προσώπου Ἠσαὺ τοῦ ἀδελφοῦ αὐτοῦ.

Y edificó allí un altar, y llamó al lugar El-Beth-el, porque allí le había aparecido Dios, cuando huía de su hermano.

There Jacob built an altar, and he called that place El-bethel, because it was there that God had revealed Himself to Jacob as he fled from his brother.
