Yirmeyahu (Jeremiah) 7:22-23

“For I did not speak to your fathers, or command them in the day that I brought them out of the land of Mitsrayim, about matters of ascending offerings or slaughterings. “But this word I did command them, saying, ‘Obey My voice, and I shall be your Elohim, and you be My people. And walk in all the ways that I have commanded you, so that it be well with you.’
