'Heart' in the Bible

Jehu aimed his bow and shot an arrow right between Jehoram's shoulders. The arrow went through his heart and he fell to his knees in his chariot.

The king stood by the pillar and renewed the covenant before the Lord, agreeing to follow the Lord and to obey his commandments, laws, and rules with all his heart and being, by carrying out the terms of this covenant recorded on this scroll. All the people agreed to keep the covenant.

No king before or after repented before the Lord as he did, with his whole heart, soul, and being in accordance with the whole law of Moses.
