Exodus 23:13-15

Amplified Bible

¹³ Now concerning everything which I have said to you, be on your guard; do not mention the name of other gods [either in a blessing or in a curse]; do not let such speech be heard [coming] from your mouth.

Three National Feasts

¹⁴ “Three times a year you shall celebrate a feast [dedicated] to Me. ¹⁵ You shall observe the Feast of Unleavened Bread; for seven days you shall eat unleavened bread, as I commanded you, 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 [but you shall bring sacrificial offerings].
