“our hearts melted”

This is what a harlot Rahab said to two spies whom Joshua sent secretly to Jericho:

“… all the inhabitants of the land have melted away before you.  …

When we heard it, our hearts melted and no courage remained in any man any longer. ….”

[Reason: It was because Rahab and all the inhabitants of Jericho heard

how the Lord dried up the water of the Red Sea before the Israelites when they came out of Egypt

and what the Israelites did to the two kings of the Amorites who were beyond the Jordan] (Josh. 2:9-11)

The hearts of all the kings of the Amorites who were beyond the Jordan to the west,

And of all the kings of the Canaanites who were by the sea

melted and there was no spirit in them any longer.

[Reason: It was because they heard how the Lord had dried up the waters of the Jordan

before the sons of Israel until they had crossed (5:1)]

The hearts of the Israelites melted and became as water.

[Reason: It was because they lost the war against the men of Ai due to Achan’s sin] (7:5)
