시편 12:9 미드라쉬: Ein Yaakov (Glick Edition), Midrash Tehillim & Vayikra Rabbah

R. Chelbo in the name of R. Huna said: "Whoever prays with his back turned to the synagogue is to be called wicked, as it is said (Ps. 12, 9.) On every side do the wicked walk." Abaye said: "This refers only to one who does not turn his face towards the synagogue but if he does turn his face towards the synagogue it does not matter even if his back is towards the worshipers." There was one man who prayed with his back turned to the synagogue; Elijah happened to pass by. It seemed to Elijah that the man prayed in the manner of an Arabian merchant, and he said to him: "Art thou standing before thy Master as if there were two dominions?" Thereupon Elijah drew his sword and killed the man.

R. Jochanan and R. Elazar both said: "When a man must apply for help to his fellow-men, his face changes like [the worm called] Kerum; as it is said (Ps. 12, 9.) Like a worm, so is the cheapness of the sons of men." What is Kerum? When R. Dimi came he related that among the sea-coast towns, there is a certain worm, the name of which is 'Kerum', and when the sun shines upon him, he changes into various colors. R. Ami and R. Ashi both say: "He [who has to apply for charity] is as if two judgments were passed upon him — those of fire and water, as it is said (Ps. 66, 12.) Thou hast caused man to ride on our heads; we entered into fire and into water."

The original text is in Hebrew and it is a conversation between two rabbis, Rabbi Yehuda and Rabbi Nechemia. Rabbi Yehuda says, "Around the wicked they will walk, as it says (Isaiah 66:24), 'And they shall go forth and look upon the carcasses of the men that have transgressed against Me.' At that time, the righteous will give thanks to God for the suffering that He brought upon them in this world, as it says (Isaiah 12:1), 'And in that day thou shalt say: I will give thanks unto Thee, O LORD; for though Thou wast angry with me, Thine anger is turned away, and Thou comfortest me.' The vineyard is written for the righteous, as it says (Psalms 80:15), 'The vineyard of the LORD of hosts is the house of Israel.' Rabbi Nechemia challenges Rabbi Yehuda's interpretation of the verse and says, "How long will you interpret the verse in this manner? Rather, the wicked will walk around the righteous, as it says (Psalms 92:8), 'When the wicked spring up as the grass, and when all the workers of iniquity do flourish; it is that they may be destroyed for ever.' When the wicked leave Gehenna and see the righteous in Gan Eden, their souls will diminish. This is what is written (Psalms 112:10), 'The wicked shall see it, and be vexed; he shall gnash with his teeth, and melt away.' When God announces the commandments that were belittled in this world, that is when shame will befall humans. God will say, 'Why should you be stoned for keeping the Sabbath? Why should you be burned for eating matzah? Why should you be killed for wearing tzitzit? Why should you be stabbed with a spear for fulfilling My will?' (Zechariah 13:6) And he shall say, 'These are the wounds with which I was wounded in the house of my friends.' These wounds caused me to love my Father in Heaven. Woe to those who belittle the commandments in this world." [Source: Babylonian Talmud, Tractate Brachot 10a.]
