Now that Hashem had warned him not to speak with Yaakov good or bad, why did he continue to chase him?
Oznayim la'Torah: He still had in mind to kill Yaakov, and caught up with him, in the hope that Hashem would change his mind and allow him to do so. 1
Oznayim la'Torah: Just like Bil'am - Refer to Bamidbar 22:20:2:1.
Why didn't the Torah specify on which mountain Yaakov pitched his tent?
Bechor Shor, Ibn Ezra: The Torah revealed that Lavan pitched in Har ha'Gil'ad, and the same applies to Yaakov.
Who were Lavan's "brothers" that he stuck in Har ha'Gilad?
Refer to 31:23:1.
What are the meanings of "Taka Es Aholo" and "Taka Es Echav"?
Sechel Tov: Both mean "he pitched his tent." It says "brothers" regarding Lavan, for he did not have a big camp, just he and his brothers.
Targum Onkelos, Targum Yonasan: Yaakov spread his tent, and Lavan caused his brothers to lodge.
Ibn Ezra: It says "tent" regarding Yaakov, and the same applies to Lavan; "Es Echav" means "with his brothers."
Alshich: Yaakov pitched his tent (and went alone to speak to Lavan). Lavan [had gathered his 'brothers' to spill blood, but now he repented, so he] left them (and went alone to speak to Yaakov. Malbim - this was due to Hashem's warning.)
Ha'amek Davar: Yaakov pitched his tent, for his camp needed to rest. Lavan could run, and did not need a tent; he fixed his place in the mountain.
