'Devoted' in the Bible

"Now as for you, my son Solomon, get to know the God of your father. Serve him with a sound heart and a devoted soul, because the LORD is searching every heart, every plan and thought. He will be found by you, assuming you are seeking him, but if you abandon him, he will abandon you forever.

Then the people rejoiced because they had given voluntarily, since with a devoted heart they had freely given to the LORD.

granting to my son Solomon to keep with a devoted heart your commands, your decrees, and your statutes, carrying out all of them, and that he may build the Temple for which I have made the preparations.
