Leaving Beer Sheva
As a result of Yitzchak's command that Yackov marry a women from his family, he left Beer Sheva, leaving a large vacuum and taking with him its beauty, majesty and spender, for now it lacked its righteous resident. Yackov left with the intent to go to Charan.
Yackov arrived at the location of Mount Moriah, the mountain having moved towards him and He prayed there establishing the nightly prayer of Mariv. Yackov lodged there because the sun had set suddenly not at its usual time, in order that he should sleep there. He took some of the stones of the place and placed them surrounding his head like a drainpipe out of fear of wild beasts. For the first time in 14 years Yackov lay down to sleep, as all the years he served in the House of Ever, he would sleep sitting since he was engaged in Torah study. As he lay down in that place, the stones started quarreling with one another, each wanting the Tzadik to lay his actual head on them. Hashem therefore transformed the stones into a single stone.
Crossing the Jordan River
Yackov placed his staff in the river and it split into two, allowing him to cross.
Escape from Lavan
When the forces of evil attack a person and he fights back, not only is he able to recover the energy they stole from him, he is able to extract energy that was buried deep inside of them from what they had previously captured. Therefore when Yaakov battled Lavan he was able to extract from him massive amounts of holy energy that manifested as his four wives, the twelve tribes and great wealth.
