The Context

“And the youths grew up, and Eisav was a man who understood hunting, a man of the field, whereas Yaakov was an innocent man, dwelling in tents.” (Bereishis 25:27) The Zohar teaches that the growth mentioned in this verse is spiritual growth. During his childhood, Eisav followed the path of Avraham and Yitzchak, it was only after reaching maturity that he veered off on his sinful path.
