Midrash Tanchuma
With1The prefix bet in the first word of the Torah can be translated as “with,” “in,”, “by means of,” etc. the beginning (Gen. 1:1). This is what Scripture means when it says: The Lord with wisdom2“Beginning” and “wisdom” are synonyms for “Torah” in rabbinic literature. See Schechter, Aspects of Rabbinic Theology, p. 129. founded the earth (Prov. 3:19). That is, when the Holy One, blessed be He, was about to create this world, He consulted the Torah3Seven things were created two thousand years before the creation of heaven and earth, and the Torah was one of them. before embarking upon the work of creation, as it is said: Counsel is mine and sound wisdom; I am understanding, power is mine (ibid. 8:14). How was the Torah written? It was written with letters of black fire on a surface of white fire, as is said: His locks are curled and black as a raven (Song 5:11). What is meant by His locks are curled?4The word taltalim (“curls”) is read as tille tillim (“heaps upon heaps”). Each letter in the Torah has numerous strokes upon it which, according to tradition, represent heaps upon heaps of laws. Cf. Leviticus Rabbah 19:2, Song of Songs Rabbah 5:11–12. It means that each crowned stroke on the letters of the Torah contains heaps and heaps of law. For example, it is written in the Torah: Profane not My Holy Name (Lev. 22:2); but if you should change the het in the word yehallelu (“profane”) into a heh, the word would read “praise,” and you would thereby destroy the world. Conversely, where it is written Let everything that hath breath praise the Lord (Ps. 150:6), if you should alter the heh in the word tehallel (“praise”) into a het, the word would read “profane,” and you would thereby destroy the world.
Midrash Tanchuma
Similarly, in the verse Hear, O Israel, the Lord our God, the Lord is One (Deut. 6:4), if you should change the dalet in the word ehad (“one”) into a resh, the word would then read aher (“another”), and you would thereby destroy the world, since it is said: For thou shalt not bow to another god (Exod. 34:14). Likewise, in the verse They have lied against the Lord (Jer. 5:12), if you should change the preposition bet (“against”) into the preposition kaf (“like”), you would thereby destroy the world.
Midrash Mishlei
[10](Proverbs 1:15): "My son, do not walk in the way with them" - this refers to the nations of the world, as it is said of them (Leviticus 20:23): "And you shall not walk in the customs of the nations." "Hold back your foot from their path" - so as not to worship their idolatry, as it is said (Exodus 34:14): "For you shall not bow down to another god." (Proverbs 1:16): "For their feet run to evil" - this refers to idolatry, "and they make haste to shed blood" - to teach you that anyone who worships idolatry is as if he sheds blood.
