'Take Heed' in the Bible
Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes saw, and lest they depart from thy heart all the days of thy life; but make them known unto thy children and thy children's children;
Take heed unto yourselves, lest ye forget the covenant of Jehovah your God, which he made with you, and make you a graven image in the form of anything which Jehovah thy God hath forbidden thee.
Take heed to yourselves, lest your heart be deceived, and ye turn aside, and serve other gods, and worship them;
Take heed to thyself that thou offer not thy burnt-offerings in every place that thou seest;
Take heed to thyself that thou forsake not the Levite as long as thou livest in thy land.
take heed to thyself that thou be not ensnared to follow them, after that they are destroyed from before thee; and that thou inquire not after their gods, saying, How do these nations serve their gods? even so will I do likewise.
Take heed in the plague of leprosy, that thou observe diligently, and do according to all that the priests the Levites shall teach you: as I commanded them, so ye shall observe to do.
