Jeremías 6:16 Midrash: Midrash Tehillim & Sifrei Devarim

In what way will a youth merit to guard his way, as Solomon said (Proverbs 3:6), "In all your ways acknowledge Him, and He will make your paths straight." If you know God in all matters, He will direct your ways. Similarly, David said (Psalms 16:8), "I have set the Lord always before me; because He is at my right hand, I shall not be moved." And concerning this, David also said (Psalms 30:7), "O Lord, by Your favor You have made my mountain stand strong." What enables my flesh to dwell in security? David said, "I know that deceit does not rule over my flesh." Thus, the righteous are content with no deceit, as they wait and search for what they may do to have a share in the World to Come. Therefore, David said (Psalms 16:11), "You make known to me the path of life." Similarly, Moses said to God (Exodus 33:13), "Now therefore, I pray You, if I have found grace in Your sight, show me now Your ways." And he also said (Psalms 25:5), "Guide me in Your truth, and teach me." And as it is written (Jeremiah 6:16), "Thus says the Lord: 'Stand in the ways and see, and ask for the old paths, where the good way is, and walk in it.'" See which way Abraham walked and which way Nimrod walked, and which of them succeeded. See which way Jacob walked and which way Esau walked, and which of them succeeded.

R. Meir was wont to say: When Israel were meritorious, they bore witness over themselves, viz. (Joshua 24:22) "And Joshua said to the people: Bear witness over yourselves that you have chosen the L-rd to serve Him. And they said: We are witnesses." When they went astray, viz. (Hoshea 12:1) "Ephraim has surrounded Me with falsehood, and the house of Israel with deceit," the tribe of Judah and Benjamin testified against them, viz. (Isaiah 5:3-4) "And now, dweller of Jerusalem and man of Judah. What more could have been done for my vineyard that I did not do for it?" When the tribe of Judah went astray, viz. (Malachi 2:11) "Judah has been faithless, etc.", He had the prophets bear witness against them, viz. (II Kings 17:13) "The L-rd has borne witness against Israel and Judah by the prophets of every vision, etc." When they went astray with the prophets, viz. (II Chronicles 36:16) "And they mocked the messengers of G-d and despised His prophets," He had the heavens bear witness against them, viz. (Devarim 4:26, 30:19) "I call to bear witness against you this day, the heavens." When they went astray with the heavens, viz. (Jeremiah 7:17) "Do you not see what they are doing in the cities of Judah and in the streets of Jerusalem? (18) The children are gathering wood, and the gatherers are kindling the fire, and the women are kneading dough to make cakes for the queen of heaven!" — He had the earth bear witness against them, viz. (Ibid. 6:19) "Hear, O earth, I will bring evil upon this people." When they went astray with the earth, viz. (Hoshea 12:12) "Their altars, too, are like heaps upon the furrows of he field," He had the ways bear witness against them, viz. (Jeremiah 6:16) "Place yourself on the ways and see, etc." When they went astray with the ways, viz. (Ezekiel 16:25) "At every crossroad you built your lofty place," He had the mountains bear witness against them, viz. (Michah 6:2) "Hear, O mountains, the quarrel of the L-rd." When they went astray with the mountains, viz. (Hoshea 4:13) "They slaughter offerings upon the mountaintops," He had the nations bear witness against them, viz. (Jeremiah 6:18) "Therefore, hear, O nations, etc." When they went astray with the nations, viz. (Psalms 106:35) "and they mingled with the nations and learned their deeds," He had a beast bear witness against them, viz. (Isaiah 1:3) "The ox knows its owner, and the ass, its master's trough, but Israel does not know, etc." When they went astray with the beast, viz. (Psalms 106:20) "They exchanged their glory for the likeness of an ass, eating grass," He had the animal bear witness against them, viz. (Jeremiah 8:7) "Even the stork in the heavens knows its seasons … but My people do not know the law of the L-rd." When they went astray with the animal, viz. (Ezekiel 8:10) "And I came and I saw, and behold, every sort of image — disgusting creeping things and animals, etc.", He had the fish bear testimony against them, viz. (Iyyov 12:8) "Or speak to the earth and it will teach you; the fish of the sea will report to you, etc." When they went astray with the fish, viz. (Tzephaniah 1:3) "… and the fish of the sea and the stumbling blocks of the wicked," He had the ant bear witness against them, viz. (Proverbs 6:6-8) "Go to the ant, you sluggard, see its ways and grow wise. Though it has no officer … she prepares her food in the summer, etc." R. Shimon b. Elazar says: "Wretched is man, who must learn from the ant!" If he learned and acted (accordingly) would he be "wretched"? Rather, he should learn from its ways, but does not.
