'Hearts' in the Bible

We heard [this], and our hearts melted, and {no courage was left in anyone} because of your presence. For Yahweh your God [is] God in the heavens above and on the earth below.

And 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 Yahweh dried up the waters of the Jordan in front of the {Israelites} until they crossed [over], their hearts melted, and {there was no courage left in them} because of the presence of the {Israelites}.

The men of Ai killed about thirty-six of them, and they chased them from the gate up to Shebarim and killed them on the slope. And the hearts of the people melted and became like water.

For it was Yahweh that {hardened their hearts}, to meet Israel in war in order to utterly destroy them without mercy, that they would destroy them just as Yahweh commanded Moses.

My companions who went up with me made the hearts of the people melt, but I remained true to Yahweh my God.

Look! {I am about to die}, and you know in all your hearts and souls that not one thing {failed} from all the good things that Yahweh your God promised concerning you; everything {has been fulfilled}; {not one thing failed}.

He said, "Remove the foreign gods that [are] in your midst, and incline your hearts to Yahweh the God of Israel."
