'Take Heed' in the Bible

And He said to them, Take heed what you hear. With that measure which you measure, it shall be measured to you. And to you who hear, more shall be given.

And He charged them, saying, Take heed! Beware of the leaven of the Pharisees and of the leaven of Herod.

But take heed to yourselves. For they shall deliver you up to sanhedrins, and in the synagogues you shall be beaten. And you shall be brought before rulers and kings for My sake, for a testimony against them.

But take heed; behold, I have told you all things beforehand.

Take heed, watch and pray, for you do not know when the time is.
