'Take Heed' in the Bible

And he said to them, Take heed what ye hear. With what measure ye mete, it will be measured to you, and more will be added to you.

And he charged them, saying, Take heed, beware of the leaven of the Pharisees, and the leaven of Herod.

But do ye take heed to yourselves; they will deliver you up to councils, and ye will be taken into synagogues and beaten; and ye will be brought before governors and kings for my sake, for a testimony to them.

But do ye take heed! I have told you all beforehand.

Take heed, watch; for ye know not when the time is.
