Midras Mazmur 62:2: Midrash Tehillim

For the conductor, on the hands of the dove. Yet my soul is silent only to God. This is what the scripture says (Isaiah 26:4), "Trust in the LORD forever, for the LORD, the LORD himself, is the Rock eternal." The Holy One, blessed be He, says, "Do you know in whom you trust? You trust in the One who created two worlds with two letters, as it says (Psalms 89:27), 'The God who is the Rock of Israel said, "I will be their Father."' And it says (Isaiah 43:10), 'Before me no god was formed, nor will there be one after me.'" This world was created with the letter "Heh." As it says (Genesis 2:4), "These are the generations of the heavens and the earth when they were created, on the day that the LORD God made earth and heaven." It says "Heh" - "they were created." And the World to Come was created with the letter "Yud." Therefore, it says, "The LORD is the Rock eternal," meaning, the world was created with His name. And why was this world created with the letter "Heh"? Just as when a person speaks the letter "Heh," there is no sensation of the lips or effort of the tongue, so too did the Holy One, blessed be He, create His world effortlessly and without toil, as it says (Psalms 33:6), "By the word of the LORD the heavens were made, their starry host by the breath of his mouth." And it says (Isaiah 57:15), "For this is what the high and exalted One says-- he who lives forever, whose name is holy: 'I live in a high and holy place, but also with the one who is contrite and lowly in spirit, to revive the spirit of the lowly and to revive the heart of the contrite.'" And afterwards, it says (Isaiah 26:5), "He will humble the haughty and bring down the exalted city; he will level it to the ground and destroy it completely." And afterwards (Micah 4:13), "Rise and thresh, Daughter Zion, for I will give you horns of iron; I will give you hooves of bronze, and you will break to pieces many nations." Thus said the Holy One, blessed be He, to Israel, "I am your Redeemer, but you must work. And what do I make you work on? On the laws and the courts that I have given you." Therefore, it says, "On the hands of the dove."

However, to God my soul is likened, for from Him comes my salvation. As it says (2 Chronicles 20:12), "For we have no power against this great multitude that is coming against us; nor do we know what to do, but our eyes are upon You." He is my rock and my salvation. What is my rock? When adversity comes upon me in this world, in return for the adversity that comes upon me, He will save me. My refuge will not falter greatly. Gehenna is called a great place where the wicked fall and cannot stand. As it says (Joel 4:13-14), "Put in the sickle, for the harvest is ripe. Come, go down; for the winepress is full, the vats overflow--for their wickedness is great." Multitudes, multitudes in the valley of decision! For every one of them the day of judgment is like the decision of the winepress. At that time, my refuge will not falter greatly. As it says (Joel 4:16), "The Lord also will roar from Zion, and utter His voice from Jerusalem; the heavens and earth will shake; but the Lord will be a shelter for His people, and the strength of the children of Israel." Similarly, the sons of Korah say (Psalm 46:7), "The nations raged, the kingdoms were moved; He uttered His voice, the earth melted. The Lord of hosts is with us; the God of Jacob is our refuge. Selah."
