Our verse says that that they never feared Hashem. Verse 33 said that they feared Hashem!
Rashi: They did not fully fear Hashem like the law of Yisrael. Even though they converted due to fear of the lions 1 , they continued to act like before conversion. They served idolatry, like the Kohen, who was from the Shomronim, taught them.
Radak, Malbim: The verse discusses the exiled Yisraelim. They never repented. They still serve idolatry. Yir'as Hashem is serving only Hashem (Yehoshua 24:4, Shmuel I, 12:24). Malbim - however, Nochrim may serve both, with proper intent, and this is Yir'as Hashem (refer to 17:18:1:1).
Why does it say "Asher Sam Shmo Yisrael"?
Radak: After Yakov told his sons "remove the foreign gods amidst you 1 and change your clothes", Hashem appeared to him and said that he will be called Yisrael (Bereishis 35:2, 10).
Malbim: "Yisrael" is based on "Sarisa Im Elohim" (Bereishis 32:29; you overcame an angel; you are above every Sar and Mazal, therefore you are forbidden to serve b'Shituf).
That they took from Shechem after they killed all the men. (PF)
