'Soul' in the Bible

The king stood beside a pillar and made a covenant in the presence of the LORD: to follow after the LORD, to keep his commandments, his testimonies, and his statutes with all of his heart and soul, and to carry out what was written in the covenant contained in the book. All the people consented to enter into the covenant.

There had been no king like him before him, who turned to the LORD with all his heart, with all his soul, and with all his strength, in obeying everything in the Law of Moses. No king arose like Josiah after him.
