'Heed' in the Bible

And command thou the people, saying, Ye are to pass through the coast of your brethren the children of Esau, which dwell in Seir; and they shall be afraid of you: take ye good heed unto yourselves therefore:

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

Take ye therefore good heed unto yourselves; for ye saw no manner of similitude on the day that the LORD spake unto you in Horeb out of the midst of the fire:

Take heed unto 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 be 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 spake unto all Israel, saying, Take heed, and hearken, O Israel; this day thou art become the people of the LORD thy God.
