Yaakov spends 20 years in the house of Lavan, after which he starts heading home. He sends messengers ahead to check on his brother Eisav (Bereishis 32:4). The messengers return and inform Yaakov that Eisav is approaching with an army of sorts (Bereishis 32:7).
After 20+ years, why was Eisav just now coming, at exactly the moment when Yaakov was leaving? Did Eisav depart towards Yaakov as a result of the messengers that Yaakov sent to him?
