'Dry' in the Bible

The priests who were carrying the Ark of the Covenant of the LORD stood firm on dry ground in the middle of the Jordan River, while all Israel crossed on dry ground until the entire nation had finished crossing the Jordan River.

As soon as the priests who were carrying the Ark of the Covenant of the LORD had come up from the middle of the Jordan River, and the soles of the priests' feet came up to dry ground, the water of the Jordan River returned to normal, covering its banks as it had done so before.

you are to tell your descendants: "Israel crossed this Jordan River on dry ground

Look at our bread: it was still warm when we took it from our houses as our food for our journey on the very day we set out to come to you. But now, look how it's dry and moldy.
