나로 내 손자들과 딸들에게 입맞추지 못하게 하였느냐 네 소위가 실로 어리석도다
Akeidat Yitzchak
Since Jacob's return to Eretz Yisrael was initiated at the request of G-d, and G-d had not yet given any hint of His assistance in the forthcoming confrontation with Esau, we can understand why some commentators look for something in Jacob's conduct which caused G-d’s displeasure. These conflicting views are even reflected in the Midrash Rabbah. According to the opinion that the messengers sent by Jacob were angels, one cannot fault Jacob's conduct, else angels would not have been placed at his disposal.
