3You may work for six days each week, but on the seventh day you must not do any work. You must rest. It is a sacred/holy day when you must gather together to worship me. Wherever you live, you must rest on that day.
4There are festivals that I have established for you. Those will also be sacred/holy days when you must gather together to worship me.
5The first festival is ◄the Passover/when you remember that I spared your ancestors when I killed all the firstborn Egyptian sons►. That festival will begin at twilight/dusk/sunset on the chosen day ◄each spring/in March or April each year►, and end on the following day.
6The next day, the Festival of Eating Bread That Has No Yeast will begin. That festival will continue for seven days. During that time, the bread that you eat must be made without yeast.
