The secret of Shecem
(ו) וַיַּעֲבֹ֤ר אַבְרָם֙ בָּאָ֔רֶץ עַ֚ד מְק֣וֹם שְׁכֶ֔ם עַ֖ד אֵל֣וֹן מוֹרֶ֑ה וְהַֽכְּנַעֲנִ֖י אָ֥ז בָּאָֽרֶץ׃
(6) Abram passed through the land as far as the site of Shechem, at the terebinth of Moreh. The Canaanites were then in the land.

והכנעני אז בארץ. יתכן שארץ כנען תפשה כנען מיד אחר ואם איננו כן יש לו סוד והמשכיל ידום:

AND THE CANAANITE WAS THEN IN THE LAND. It is possible that the Canaanites seized the land of Canaan from some other tribe at that time.14The Canaanite was then, not before this, in the land. Cf. Rashi: “The Canaanite was then engaged in conquering the land of Israel from the seed of Shem.” Should this interpretation be incorrect, then there is a secret meaning to the text. Let the one who understands it remain silent.15

The existence of The Canaanites in Nabuls(which is the explanation of "Shechem" according to jewish commentators ) is a fact in the story of Abraham. The problem of the word (then) is that it indicates that the Canaanites were not there at the author's time , which is not correct if it was Moses , since they remained in the land until Joshua conquered it. Whoever read bin Ezra comment thought that the secret was : ( the verse was written by someone else) , but this is not the case , since its no problem for the jews , they already said that deutronomy 34 was written by joshua , according to the talmud . Whats bin Ezra's secret ? I claim that i know it , and from Allah i seek help. The only exit is that its not Nabuls , but another holy place , or a "mə·qō·wm = קוֹם֣מ = ְم " as the hebrew says. Its the ( place of Abraham = اا م ( which he returned to in Genesis 13:4 and summomed to pilgrimage (called on the name of the Lord.) which is today in Mecca , the islamic pilgrima

(5) So Moses the servant of the LORD died there, in the land of Moab, at the command of the LORD.

The Gemara elaborates on the particulars of this baraita: The Master said above that Joshua wrote his own book and eight verses of the Torah. The Gemara comments: This baraita is taught in accordance with the one who says that it was Joshua who wrote the last eight verses in the Torah. This point is subject to a tannaitic dispute, as it is taught in another baraita: “And Moses the servant of the Lord died there” (Deuteronomy 34:5); is it possible that after Moses died, he himself wrote “And Moses died there”? Rather, Moses wrote the entire Torah until this point, and Joshua wrote from this point forward; this is the statement of Rabbi Yehuda. And some say that Rabbi Neḥemya stated this opinion.
