'Carefully' in the Bible

Then you will succeed if you carefully follow the statutes and ordinances the Lord commanded Moses for Israel. Be strong and courageous. Don’t be afraid or discouraged.

So now, in the sight of all Israel, the Lord's assembly, and in the hearing of our God, I say this: Carefully observe all the commands of the Lord your God, so that you may possess this good land and may leave it as a permanent inheritance for your children after you.
