פירושים על בראשית 28:2: רש״י, רמב״ם, אבן עזרא ועוד

פדנה is the same as לפדן to Padan;

קום לך, the word קום is not to be understood literally as “rise!,” but as an instruction to go about the task to be fulfilled with speed, without delay.
פדנה ארם, we explained this as meaning “to Charan.”

Any word that requires a ל prefix... It does not mean just any word, as we find this rule applies only to names of places and countries, such as בבלה and חברונה, and sometimes to vessels, such as המזבחה.
