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:

Read Exodus 13:5 Using Other Translations

And it shall be when the LORD shall bring thee into the land of the Canaanites, and the Hittites, and the Amorites, and the Hivites, and the Jebusites, which he sware unto thy fathers to give thee, a land flowing with milk and honey, that thou shalt keep this service in this month.
And when the LORD brings you into the land of the Canaanites, the Hittites, the Amorites, the Hivites, and the Jebusites, which he swore to your fathers to give you, a land flowing with milk and honey, you shall keep this service in this month.
You must celebrate this event in this month each year after the LORD brings you into the land of the Canaanites, Hittites, Amorites, Hivites, and Jebusites. (He swore to your ancestors that he would give you this land—a land flowing with milk and honey.)
