'Careful' in the Bible

The Lord says, 'Be very careful if you value your lives! Do not carry any loads in through the gates of Jerusalem on the Sabbath day.

If you are careful to obey these commands, then the kings who follow in David's succession and ride in chariots or on horses will continue to come through the gates of this palace, as will their officials and their subjects.

But you should take careful note of this: If you put me to death, you will bring on yourselves and this city and those who live in it the guilt of murdering an innocent man. For the Lord has sent me to speak all this where you can hear it. That is the truth!"
