'Following the Lord' in the Bible

Now after the time that Amaziah did turn away from following the LORD they made a conspiracy against him in Jerusalem; and he fled to Lachish: but they sent to Lachish after him, and slew him there.

And Josiah took away all the abominations out of all the countries that pertained to the children of Israel, and made all that were present in Israel to serve, even to serve the LORD their God. And all his days they departed not from following the LORD, the God of their fathers.
