'Take Heed' in the Bible

Only take heed to yourself, and keep your soul diligently, lest you forget the things which your eyes saw, and lest they depart from your heart all the days of your life; but make them known to your children and your children's children;

Take heed to yourselves, lest you forget the covenant of Yahweh your God, which he made with you, and make you an engraved image in the form of anything which Yahweh your God has forbidden you.

Take heed to yourselves, lest your heart be deceived, and you turn aside, and serve other gods, and worship them;

Take heed to yourself that you don't offer your burnt offerings in every place that you see;

Take heed to yourself that you don't forsake the Levite as long as you live in your land.

take heed to yourself that you not be ensnared to follow them, after that they are destroyed from before you; and that you not inquire after their gods, saying, "How do these nations serve their gods? I will do likewise."

Take heed in the plague of leprosy, that you observe diligently, and do according to all that the priests the Levites shall teach you: as I commanded them, so you shall observe to do.
