'Take Heed' in the Bible

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

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

And Jesus answering said, Take heed lest any deceive you.

But take heed to yourselves for they will deliver you to councils, and ye shall be beaten in synagogues, and shall be brought before rulers and kings for my sake, for a testimony to them.

Take heed; watch and pray: for ye know not when the time is.
