In the 8th ikkar in the Rambam's introduction to Perek Chelek, he writes:
ואין הפרש בין "וּבְנֵי חָם כּוּשׁ וּמִצְרַיִם וּפוּט וּכְנָעַן" (בראשית י ו), "וְשֵׁם אִשְׁתּוֹ מְהֵיטַבְאֵל בַּת מַטְרֵד" (שם לו לט), "וְתִמְנַע הָיְתָה פִילֶגֶשׁ" (שם לו יב), ובין "אָנֹכִי יְיָ" (דברים ה ו) ו"שְׁמַע יִשְׂרָאֵל יְיָ אֱלֹהֵינוּ יְיָ אֶחָד" (שם ו ד). כי הכל מפי הגבורה, והכל תורת ה' תמימה, טהורה וקדושה, אמת
And there is no difference between "And the sons of Cham were Kush and Mitsrayim" (Genesis 10:6), "and his wife's name was" Meheitabel" (Genesis 36:39), "And Timnah was his concubine" (Genesis 36:12) [ on the one hand] and "I am the Lord, your God" (Exodus 20:2) and "Hear Israel" (Deuteronomy 6:4) [on the other]; since they are all from the mouth of the Almighty and it is all the Torah of God - complete, pure and holy truth.
The verse "And Timnah was his concubine" (Genesis 36:12) is taken from Esav’s genealogy in chapter 36 and, and "I am the Lord, your God" (Exodus 20:2) is from the Ten Commandments. Here Maimonides clearly equates the two.
