'Careful' in the Bible

"Pay careful attention to your duties, because you are judging not only for the sake of human beings but also for the LORD and he is present with you as you make your rulings.

and "I won't let Israel's foothold slip on the land that I've given to your ancestors, if only they will be careful to keep everything that I commanded them in the Law, in the statutes, and in the ordinance through Moses."
