After he was called by God, Jacob ascends to Bethel, that is, to the house of God (this is how the name Bethel is interpreted), offers sacrifices to God and is declared chief and master of the holy rites. He teaches his successors and descendants how they must enter the house of God. He orders the foreign gods to be rejected like dung and filth and to change the garments. It is fitting for us to do likewise when we are called before God, or enter the divine temple, especially in the time of the holy baptism. We, as if we drive away the foreign gods and part from such error, must assert, ―I refuse you, Satan, and all your pomp and all your worship.‖ We also must change completely our garment by stripping off ―the old self that is corrupt through deceitful lusts‖1 and by clothing ourselves with ―the new self, which is being renewed in knowledge according to image of its Creator.‖2 The women who were with Jacob took off their earrings. And in fact women by entering the house of God without wearing any carnal ornament and with loose hair remove from their head any accusation of pride. That is why, I believe, those women took off the precious stones they wore in their ears―St Cyril of Alexandria

Therefore Jacob, who had purified his heart of all pretenses and was manifesting a peaceable disposition, first cast off all that was his, then remained behind alone and wrestled with God. For whoever forsakes worldly things comes nearer to the image and likeness of God. What is it to wrestle with God other than to enter upon the struggle for virtue, to contend with one who is stronger and to become a better imitator of God than the others are? Because Jacob‘s faith and devotion were unconquerable, the Lord revealed his hidden mysteries to him by touching the side of his thigh. For it was by descent from him that the Lord Jesus was to be born of a virgin, and Jesus would be neither unlike nor unequal to God. The numbness in the side of Jacob‘s thigh foreshadowed the cross of Christ, who would bring salvation to all people by spreading the forgiveness of sins throughout the whole world and would give resurrection to the departed by the numbness and torpidity of his own body. On this account the sun rightly rose on holy Jacob, for the saving cross of the Lord shone brightly on his lineage. And at the same time the Sun of justice rises on the person who recognizes God, because he is himself the everlasting Light—St Ambrose of Milan

Notice here, I ask you, the extraordinary care of the loving God. When he saw [Jacob] consenting to the journey in accordance with his mother‘s advice, which came out of fear of his brother, and taking to the road like some athlete, with no support from any source, leaving everything instead to help from on high, Christ wanted at the very beginning of the journey to strengthen Jacob‘s resolve. And so he appeared to him with the words "I am the God of Abraham and the God of your father Isaac." I have caused the patriarch and your father to experience a great increase in prosperity; so, far from being afraid, believe that I am he who fulfilled my promises and will shower on you my care—St John Chrysostom
