'Heart' in the Bible

And it came to pass, when all the kings of the Amorites, that were beyond the Jordan westward, and all the kings of the Canaanites, that were by the sea, heard how that Jehovah had dried up the waters of the Jordan from before the children of Israel, until we were passed over, that their heart melted, neither was there spirit in them any more, because of the children of Israel.

Forty years old was I when Moses the servant of Jehovah sent me from Kadesh-barnea to spy out the land; and I brought him word again as it was in my heart.

Nevertheless my brethren that went up with me made the heart of the people melt; but I wholly followed Jehovah my God.

Only take diligent heed to do the commandment and the law which Moses the servant of Jehovah commanded you, to love Jehovah your God, and to walk in all his ways, and to keep his commandments, and to cleave unto him, and to serve him with all your heart and with all your soul.

Now therefore put away,'said he , the foreign gods which are among you, and incline your heart unto Jehovah, the God of Israel.
