Midrasch zu Bereschit 32:9

(I Kings 18, 3) And Achab called Obadiah, who was the superintendent of the house. Now Obadiah feared the Lord greatly. What was their discussion? R. Isaac said: "Achab said to Obadiah: "Concerning Jacob, it is written (Gen. 30, 27) The Lord hath blessed me for thy sake, and concerning Joseph it is written (Ib. 39, 5) The Lord blessed the Egyptian's house for the sake of Joseph. I, however, keep thee in my house, yet I am not blessed for thy sake. Perhaps thou art not fearing God?" Thereupon a heavenly voice was heard, saying: "Obadiah fears the Lord greatly, but the house of Achab is not destined for blessings." Raba said: "What is said of Obadiah is of greater signifieanee than what is said of Abraliam, for about Abraham it is not written 'greatly,' and about Obadiah 'greatly' is added." R. Isaac said: Why did Obadiah merit to be rewarded with prophecy? Because he hid one hundred prophets in a cave, as it is written (I Kings, 8, 4) And it happened when Isabel cut off the prophets of the Lord that Obadiah took a hundred prophets, and hid them fifty in one cave, and provided them with bread and water." Why fifty?" R. Elazar said: "He learned this from Jacob, as it is said (Gen. 32, 9) Then the other band which is left may escape." R. Abahu, however, said: "Because the cave could not hold more than fifty."

Another interpretation (of Gen. 32:8 [7]): AND JACOB WAS < GREATLY > AFRAID. Our masters have said: His body became like wax.²²See Gen. R. 44:3; 65:19. Moreover, the Holy Spirit cries out (in Prov. 24:10): IF YOU ARE INDOLENT IN THE DAY OF DISTRESS (TsRH), YOUR STRENGTH IS WANTING (TsR). At that time the Holy One said to him (in Is. 41:10): FEAR NOT, FOR I AM WITH YOU; BE NOT DISMAYED, FOR I AM YOUR GOD. I STRENGTHEN YOU, I HELP YOU…. I STRENGTHEN YOU through Michael; I HELP YOU through Gabriel. (Ibid., cont.:) AND I ALSO UPHOLD YOU THROUGH MY VICTORIOUS RIGHT HAND. (Gen. 28:15:) SEE, I AM WITH YOU. At that time (according to Gen. 32:8 [7]) HE DIVIDED THE PEOPLE WHO WERE WITH HIM. What did he do? He armed them within and clothed them with linen without. He prepared himself in three things: in prayer, with a gift,²³Gk.: doron. and for war. Where is it shown < that he prepared himself > with a gift? (In Gen. 32:22 [21]:) AND SO THE GIFT (MNHH) PASSED ON BEFORE HIM…. Where is it shown < that he prepared himself > for war? (In Gen. 32:9 [8]:) IF ESAU SHOULD COME < TO ONE CAMP (MHNH) AND DESTROY IT >…. Where is it shown < that he prepared himself > in prayer? (In Gen. 32:10 [9]:) THEN JACOB SAID: O GOD OF MY FATHER ABRAHAM, AND GOD OF MY FATHER ISAAC…. What is written after that (in vss. 11-12 [10-111])? I AM UNWORTHY OF ALL THE KINDNESSES AND ALL THE FIDELITY…. PLEASE DELIVER ME FROM THE HAND OF MY BROTHER, FROM THE HAND OF ESAU. The Holy One said to him: You have called to me. By your life, I will save you, according to what is stated (in Ps. 89:27 [26]): HE SHALL CRY TO ME, YOU ARE MY FATHER, MY GOD, AND THE ROCK OF MY SALVATION.
