Midrash sa Mga Awit 139:7: Otzar Midrashim, Mekhilta DeRabbi Yishmael, Midrash Tanchuma & Pirkei DeRabbi Eliezer

When the righteous do His will, they increase His strength and might, as it says "Now may the power of the Lord be increased" (Numbers 14:17). What does "be increased" mean? That His strength simply increases. And it says "Proclaim God's mighty acts" (Psalms 66:3), saying before Him: How goodly are Your works, O Lord... How awesome are Your deeds! Who can save himself on the Day of Great Judgment? As it says "Who can say 'I have kept my heart pure'" (Proverbs 20:9). And it says "Where can I go from Your spirit" (Psalms 139:7) and it says "In whose hand is the soul of every living thing" (Job 12:10).

Know that the Shechinah is not revealed outside the land. For it is written (Jonah 1:3) "And Jonah rose to flee to Tarshish, etc." Now can one flee from the L–rd? Is it not written (Psalms 139:7-10) "Where can I flee from Your presence … If I ascend to heaven, You are there, etc. If I take wing with the dawn, there, too, Your hand will lead me," (Zechariah 4:10) "the eyes of the L–rd range the entire land," (Mishlei 15:3) "The eyes of the L–rd see the bad and the good," (Amos 9:2) "though they dig into Sheol, though they hide in the top of the Carmel, though they go into captivity (Job 34:22) "There is no darkness nor shadow of death, etc." Rather, Jonah's intent was: I will go outside the land, where the Shechinah does not repose and reveal itself. For the gentiles are close to repentance — so that they not make Israel (who do not repent) liable (by invidious contrast). An analogy: The bondsman of a Cohein flees from his master, saying: I will go to the cemetery, a place where my master cannot come after me. His master: I have (messengers) like you. Thus, Jonah said: I will go outside the land, a place where the Shechinah is not revealed. For the gentiles are close to repentance, (this, so as not to render Israel liable by invidious contrast.) The Holy One responds: I have many messengers like you, viz. (Jonah 1:4) "Then the L–rd cast a great wind on the sea, etc."

Thereupon Cain cried out: “O Lord of the universe, do You have informers who denounce men to You? My father and mother are the only living human beings on earth, and they do not know that I slew him; how do You, who abidest in heaven, know?” The Holy One, blessed be He, answered: “Fool! I bear the entire world as it is said: I have made and I will bear; yea, I will carry and will deliver (Isa. 46:4).” Forthwith, Cain cried out: “You bear the entire world, yet my sin You are unable to bear. My sin is greater than I can bear (Gen. 4:13).” “Since you have confessed and repented,” said the Holy One, blessed be He, “go into exile from this place.” Thus it is said: And Cain went out from the presence of the Lord and dwelled in the land of Nod (ibid., v. 16). Wherever he wandered, the earth would quake beneath his feet; the animals and the beasts would tremble in fright, and would inquire of each other: “What is this?” And they would whisper: “He is Cain, who murdered his brother, Abel. The Holy One, blessed be He, has decreed concerning him: A fugitive and a wanderer you shall be.” Then they would say to each other: “Let us devour him.” They would gather together to attack, but as they approached, tears would well up in his eyes and he would cry out: Whither shall I go from Thy spirit, or whither shall I flee from Thy presence? If I ascend up into heaven, Thou art there; if I make my bed in the netherworld, behold, Thou art there. If I take the wings of morning and dwell in the uttermost part of the sea, even there would Thy hand lead me and Thy right hand hold me (Ps. 139:7–10).
