Midrash su Salmi 62:12

(Ib. b) (Ex. 34, 6), And the Lord passed by before him and proclaimed. R. Jochanan said: "Had this passage not been written, it would have been impossible to think of it, for it teaches us that the Holy One, praised be He! wrapped Himself, as does a deputy of the congregation, while pointing out to Moses the regular order of prayer, and said to him: 'Whenever Israel sins, let them do [pray to Me], after this manner, and I shall pardon their sins.'" (Ib.) The Lord, the Lord; i.e., I am the same God before a man sins as I am after he sins and does repentance; a God, merciful and gracious. R. Juda said: "This means a solemn assurance was given that the invocation of the thirteen divine attributes will never be without effect, as it is said (Ib. 10) Behold I make a covenant." Ilpha pointed out a similar contradiction: "It is written (Ex. 34, 6) abundant in goodness; and in addition it is written, and truth. How can both harmonize? In the beginning [His attribute] is truth, but at the end it is goodness." R. Elazar points out a further contradiction: "It is written (Ps. 62, 18) Unto thee, O Lord, belongeth mercy; and again. Thou renderest to every man according to his work; i.e., in the beginning He rewards every man according to his works, but in the end He is merciful." R. Huna points out a contradiction: it is written (Ib. 145, 17) The Lord is just in all His ways; and it is also written (Ib.) and kind in all His deeds; i.e., in the beginning He is only just, but in the end He is kind."

These words: This is what the verse stated, "Have I not written you thirds with counsels (moatsot) and knowledge" (Proverbs 22:20). The numerical equivalent of counsels is six hundred and six. [That,] and the seven commandments that the Sons of Noach were commanded, is six hundred and thirteen. And so [too,] does it state (Isaiah 5:1), "my beloved had a vineyard in a fertile corner": "A vineyard" - that is Israel, as it is stated (Isaiah 27:2), "a vineyard of wine, sing to it." "And he separated it" (Isaiah 5:2) - with Avraham, that he cast away the residue from him, such as Yishmael. "And he cleared it of stones" - with Yitschak, that he took Esav away from him. "And he planted it with choice vines" - that is Yaakov, as all of the plantings that came out from him were good and desirable, like this choice vine which is completely good. And this is [the meaning of] "all of it was true seed" (Jeremiah 2:21). Choice vine (sorek) has a numerical equivalent of six hundred and six, [together with] the seven commandments of the Children of Noach - behold, that is six hundred and thirteen. It is written (Proverbs 3:19), "The Lord established the earth with wisdom" - and there is no wisdom besides Torah. And what is its name? Confidant (Amon), as it is written (Proverbs 8:30), "And I was a confidant with Him." And it was not called Torah until it was given at Sinai. The numerical equivalent of Torah comes to six hundred and eleven. And the two that are subtracted from six hundred and thirteen are the two that were given by the mouth of the Almighty. And this is what is stated by the verse, "God spoke one, I heard two" (Psalms 62:12). This is [the meaning of] "Moshe commanded us the Torah" (Deuteronomy 33:4) - Moshe commanded us [commandments] according to the numerical equivalent of Torah. And the Holy One, blessed be He, commanded us the [remaining] two, as I explained in Parshat Vayishma Yitro. And it is an inheritance for Yaakov, and not for the [other] nations of the world, as it is stated (Psalms 147:19), "He tells His words to Yaakov, His statutes and His judgments to Israel, He did not do this with any nation." And it is written about it, "each day," as it is stated (Proverbs 8:30), "And I was a confidant with Him and I was His delight each day." And a day is not less than a thousand years, as it is stated (Psalms 90:4), "As a thousand years in Your eyes is like the day, yesterday." Upon what was it written before it was given? If upon silver and gold, gold and silver had not been created. Rather it was written on the forearm of the Holy One, blessed be He. And so every man [should] understand and fathom with his mind and his intelligence to contemplate the Torah day and night - as it is written (Joshua 1:8), "and you shall contemplate about it day and night" - and good deeds. And it is as the Sages said: The world is half guilty and half meritorious - if one comes and commit sins such that the sins outweigh the merits, it comes out that the world becomes guilty through him; but if the transgressions are of equal weight to the merits and one comes and performs one commandment, the merits will outweigh the transgressions. Happy is he who brings merit to the world! And if he has not learned as is fitting him, let him do his actions with faithfulness. Elihayu, may his memory be blessed, said, "I was once walking on the way and I found a man, and he was mocking me and taunting me. I said to him, 'What [can] you answer on the day of judgement, since you have not studied Torah.' He said, 'I have what to answer - it is [because of] the understanding and intelligence and heart that were not given to me from the Heavens.' I said to him, 'What is your craft?' He said to me, 'I am a trapper of birds and fish.' I said to him, 'Who gave you knowledge and heart to take flax and spin it and weave it to make traps, and to catch fish and birds with them and to sell them?' He said to me, 'It is the understanding and the knowledge that were given to me from the Heavens.' I said to him, 'To take flax and to weave and spin and catch fish and birds you were given understanding and intelligence; but to acquire the Torah, they were not given to you? Behold, it is written (Deuteronomy 30:14), "But the thing is very close to you, in your mouth and in your heart to do it."' [So] he immediately thought in his heart and raised his voice in crying. I said to him, 'My son, Let it not be bad to you, as all those that come to the world are rebuked once they come and are pulled away from Torah, as it is stated (Isaiah 19:9), "And embarrassed will be the workers of flax, the combers and weavers of holes."' And it is about him and those similar to him, and those that do like his deeds. And the last word is the fear of the Lord; and those that do it with faithfulness - his craft will be counted and he is fitting for life in the world to come.'"

(Fol. 34) (Ps. 62) Once hath God spoken, yet twice have I heard it; i.e., one biblical expression may be used for many arguments, but one and the same argument must not be deduced from different biblical expressions. It was taught in the academy of R. Ishmael (Jer. 23, 29) Like a hammer that breaketh the rock in pieces; i.e., just as the hammer strikes the stone into multitudes of pieces, so also may a biblical passage be interpreted for many arguments.
