I just realized found this little doozy today. Has anyone read the Book of Joshua? Check out the last chapter, chapter 24. The conquest is apparently all wrapped up and Joshua is speaking to the people to renew the covenant that they made at Sinai. But look what's written as he's finishing up:
כב וַיֹּאמֶר יְהוֹשֻׁעַ אֶל-הָעָם, עֵדִים אַתֶּם בָּכֶם, כִּי-אַתֶּם בְּחַרְתֶּם לָכֶם אֶת-יְהוָה, לַעֲבֹד אוֹתוֹ; וַיֹּאמְרוּ, עֵדִים. כג וְעַתָּה, הָסִירוּ אֶת-אֱלֹהֵי הַנֵּכָר אֲשֶׁר בְּקִרְבְּכֶם; וְהַטּוּ, אֶת-לְבַבְכֶם, אֶל-יְהוָה, אֱלֹהֵי יִשְׂרָאֵל. כד וַיֹּאמְרוּ הָעָם, אֶל-יְהוֹשֻׁעַ: אֶת-יְהוָה אֱלֹהֵינוּ נַעֲבֹד, וּבְקוֹלוֹ נִשְׁמָע. כה וַיִּכְרֹת יְהוֹשֻׁעַ בְּרִית לָעָם, בַּיּוֹם הַהוּא; וַיָּשֶׂם לוֹ חֹק וּמִשְׁפָּט, בִּשְׁכֶם. כו וַיִּכְתֹּב יְהוֹשֻׁעַ אֶת-הַדְּבָרִים הָאֵלֶּה, בְּסֵפֶר תּוֹרַת אֱלֹהִים; וַיִּקַּח, אֶבֶן גְּדוֹלָה, וַיְקִימֶהָ שָּׁם, תַּחַת הָאַלָּה אֲשֶׁר בְּמִקְדַּשׁ יְהוָה.
כז וַיֹּאמֶר יְהוֹשֻׁעַ אֶל-כָּל-הָעָם, הִנֵּה הָאֶבֶן הַזֹּאת תִּהְיֶה-בָּנוּ לְעֵדָה--כִּי-הִיא שָׁמְעָה אֵת כָּל-אִמְרֵי יְהוָה, אֲשֶׁר דִּבֶּר עִמָּנוּ; וְהָיְתָה בָכֶם לְעֵדָה, פֶּן-תְּכַחֲשׁוּן בֵּאלֹהֵיכֶם. כח וַיְשַׁלַּח יְהוֹשֻׁעַ אֶת-הָעָם, אִישׁ לְנַחֲלָתוֹ.
"22 Then Joshua said, "You are witnesses against yourselves that you have chosen to serve the LORD." "Yes, we are witnesses," they replied.
23 "Now then," said Joshua, "throw away the foreign gods that are among you and yield your hearts to the LORD, the God of Israel."
24 And the people said to Joshua, "We will serve the LORD our God and obey him."
25 On that day Joshua made a covenant for the people, and there at Shechem he drew up for them decrees and laws.
26 And Joshua recorded these things in the Book of the Law of God. Then he took a large stone and set it up there under the oak near the holy place of the LORD.
27 "See!" he said to all the people. "This stone will be a witness against us. It has heard all the words the LORD has said to us. It will be a witness against you if you are untrue to your God.
28 Then Joshua sent the people away, each to his own inheritance. "
The first question is naturally why they would still have any foreign gods left with them to throw away, but that can be easily answered in a few ways. The really remarkable issue is what takes place in p'sukim 25-26 where Joshua is apparently making up a covenant and laws and recording them in the God's "Sefer Torah." It's mentioned so nonchalantly in the text, but it stands in direct conflict with the popular Orthodox belief that the entire Torah was fixed and written by Moshe.
Targum Yonatan makes no changes to the words and Rashi relates one view that this is referring merely to the last eight verses of the Torah, but there is no reason to presume that. It doesn't even make any sense in context. He also relates another view that Joshua chose this time to copy the chapter on refuge cities from the Torah to his own book. But that doesn't make any sense in context either.
