'Take Heed' in the Bible

So Pharaoh said to him - Get thee from me, - take heed to thyself - do not any more! see my face, for in the day thou dost see my face, thou shalt die.

So then thou shalt set bounds for the people round about saying, Take heed to yourselves - that ye go not up into the mountain, nor touch the boundary thereof, whosoever toucheth the mountain, shall, surely die.

And, in all that I have said unto thee, shalt thou take heed to thyself, - and the name of other gods, shalt thou not mention, it shall not be heard upon thy mouth.

Take heed to thyself, Lest thou solemnise a covenant with the inhabitant of the land, whereupon, thou, art about to enter, - Lest he become a snare in thy midst;
