'Take Heed' in the Bible

Only take heed to thyself, and keep thy soul diligently, lest thou shouldst forget the things which thy eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them to thy sons, and thy sons' sons:

Take heed to yourselves, lest ye forget the covenant of the LORD your God, which he made with you, and make you a graven image, or the likeness of any thing which the LORD thy God hath forbidden thee.

Take heed to yourselves, that your heart be not 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 upon the earth.

Take heed to thyself that thou be not snared by following them, after that they are destroyed from before thee; and that thou inquire not after their gods, saying, How did 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.

And Moses and the priests the Levites spoke to all Israel, saying, Take heed and hearken, O Israel, this day thou art become the people of the LORD thy God.
