Or HaChaim on Genesis 27:36/אור החיים על בראשית כ״ז:ל״ו

1 ויאמר הכי קרא שמו יעקב, He said: "Was he not named Jacob (the crooked one)?" Esau was amazed having believed that Jacob's name referred to only a single act of subterfuge whereas he now found himself fooled by Jacob for a second time. Had Jacob's name been עקבות or something similar, Esau would not have been so surprised.

2Esau may also have meant that the name יעקב alluded to frequent use of subterfuge. So far he considered himself as having become Jacob's victim twice.
