Exodus 23:13-15

Complete Jewish Bible

¹³ “Pay attention to everything I have said to you; do not invoke the names of other gods or even let them be heard crossing your lips.

¹⁴ “Three times a year, you are to observe a festival for me. ¹⁵ Keep the festival of matzah: for seven days, as I ordered you, you are to eat matzah at the time determined in the month of Aviv; for it was in that month that you left Egypt. No one is to appear before me empty-handed.
