Exodus 15:15

Now when all the Amorite kings west of the Jordan and all the Canaanite kings along the coast heard how the LORD had dried up the waters of the Jordan before the Israelites until they had crossed over, their hearts melted and their spirits failed for fear of the Israelites.

and said to them, “I know that the LORD has given you this land and that the fear of you has fallen on us, so that all who dwell in the land are melting in fear of you.

When we heard this, our hearts melted and everyone’s courage failed because of you, for the LORD your God is God in the heavens above and on the earth below.

As smoke is blown away, You will drive them out; as wax melts before the fire, the wicked will perish in the presence of God.

and command the people: ‘You will pass through the territory of your brothers, the descendants of Esau, who live in Seir. They will be afraid of you, so you must be very careful.

These are the names of Esau’s chiefs, according to their families and regions, by their names: Chiefs Timna, Alvah, Jetheth,

She is emptied! Yes, she is desolate and laid waste! Hearts melt, knees knock, bodies tremble, and every face grows pale!

Then the officers shall speak further to the army, saying, “Is any man afraid or fainthearted? Let him return home, so that the hearts of his brothers will not melt like his own.”

Therefore all hands will fall limp, and every man’s heart will melt.

Then even the most valiant soldier with the heart of a lion will melt with fear, because all Israel knows that your father is a mighty man who has valiant men with him.
