Exodus 13:5-7

New International Version - UK

⁵ When the Lord brings you into the land of the Canaanites, Hittites, Amorites, Hivites and Jebusites – the land he swore to your ancestors to give you, a land flowing with milk and honey – you are to observe this ceremony in this month: ⁶ for seven days eat bread made without yeast and on the seventh day hold a festival to the Lord. ⁷ Eat unleavened bread during those seven days; nothing with yeast in it is to be seen among you, nor shall any yeast be seen anywhere within your borders.
