'Heart' in the Bible

When we heard this, we lost heart, and everyone’s courage failed because of you, for the Lord your God is God in heaven above and on earth below.

When all the Amorite kings across the Jordan to the west and all the Canaanite kings near the sea heard how the Lord had dried up the waters of the Jordan before the Israelites until they had crossed over, they lost heart and their courage failed because of the Israelites.

Only carefully obey the command and instruction that Moses the Lord’s servant gave you: to love the Lord your God, walk in all His ways, keep His commands, remain faithful to Him, and serve Him with all your heart and all your soul.”

“I am now going the way of all the earth, and you know with all your heart and all your soul that none of the good promises the Lord your God made to you has failed. Everything was fulfilled for you; not one promise has failed.
