Yirmeyah 7:22-23

For I spoke not unto Avoteichem, nor commanded them in the day that I brought them out of Eretz Mitzrayim, concerning olah or zevach; But this thing I commanded them, saying, Obey My voice, and I will be for you Elohim (your G-d), and ye shall be My people; and walk ye in kol HaDerech that I have commanded you, l'ma'an (in order that) it may go well with you.
