'Melted' in the Bible

When we heard it, our hearts melted [in despair], and a [fighting] spirit no longer remained in any man because of you; for the Lord your God, He is God in heaven above and on earth beneath.

Now it happened when all the kings of the Amorites who were beyond the Jordan to the west, and all the kings of the Canaanites who were by the sea, heard that the Lord had dried up the waters of the Jordan before the Israelites until they had crossed over, their hearts melted [in despair], and there was no [fighting] spirit in them any longer because of the Israelites [and what God had done for them].

The men of Ai killed about thirty-six of Israel’s men, and chased them from the gate as far as [the bluffs of] Shebarim and struck them down as they descended [the steep pass], so the hearts of the people melted [in despair and began to doubt God’s promise] and became like water (disheartened).
