Exodus 23:13-15

New Revised Standard Version, Anglicised Catholic Edition

¹³ Be attentive to all that I have said to you. Do not invoke the names of other gods; do not let them be heard on your lips.

The Annual Festivals

¹⁴ Three times in the year you shall hold a festival for me. ¹⁵ You shall observe the festival of unleavened bread; as I commanded you, you shall eat unleavened bread for seven days at the appointed time in the month of Abib, for in it you came out of Egypt.

No one shall appear before me empty-handed.
