'Devoted' in the Bible

The high places were not eliminated from Israel, yet Asa was wholeheartedly devoted to the Lord throughout his lifetime.

Certainly the Lord watches the whole earth carefully and is ready to strengthen those who are devoted to him. You have acted foolishly in this matter; from now on you will have war.

In mounting fear, Jehoshaphat devoted himself to seek the LORD. He proclaimed a period of fasting throughout all of the territory of Judah,

However, the high places were not eliminated; the people were still not devoted to the God of their ancestors.

Who among all the gods of these nations whom my fathers have devoted to destruction is he who hath been able to deliver his people out of my hand, that your God is able to deliver you out of my hand?
