Quotation על בראשית 1:2

Rabbi Berachiah said: It is written (Gen. 1:2), "the earth being tohu (unformed) and bohu (void)." What is the meaning of the word "was" in this verse? This indicates that the tohu existed previously. What is tohu? Something that confounds (taha) people. What is bohu? It is something that has substance. This is the reason that it is called "bohu", that is, "bo hu" - "it is in it."
