Rabbi Yitzḥak began: “The beginning of Your word is truth…” (Psalms 119:160) – Rabbi Yitzḥak said: Right from the beginning of the creation of the world [it can be seen that] “the beginning of Your word is truth” – “in the beginning, God created.” “But My Lord God is truth” (Jeremiah 10:10),28This verse shows that God is the epitome of truth, and it is fitting that He should establish this truth right at the beginning of the Torah.
This truth is the unity of God, as the Midrash goes on to explain. “All Your righteous laws are eternal” (Psalms 119:160) – as each and every edict that You decree upon Your creations, they accept the judgment upon themselves and receive it faithfully, and no person can come and say that two authorities created the world:29Other versions add: Or that two authorities gave the Torah. “God [Elohim] spoke [vaydaberu]” is not written here [in plural], but rather [in singular], “God spoke [vaydaber];”30Although the word Elohim is grammatically a plural form, the Torah constantly uses singular verbs with it, proving that God is indeed one.
“God [Elohim] said [vayomeru]” is not written here [in plural], but rather [in singular], “God said [vayomer]”; “In the beginning God created [bare’u]” is not written here [in plural], but rather [in singular], “God created [bara].”
