'Heed' in the Bible

But Peter, standing up with the eleven, lifted up his voice and spoke forth to them, Men of Judaea, and all ye inhabitants of Jerusalem, let this be known to you, and give heed to my words:

And he gave heed to them, expecting to receive something from them.

and said to them, Men of Israel, take heed to yourselves as regards these men what ye are going to do;

and the crowds with one accord gave heed to the things spoken by Philip, when they heard him and saw the signs which he wrought.

To whom they had all given heed, from small to great, saying, This is the power of God which is called great.

And they gave heed to him, because that for a long time he had astonished them by his magic arts.

Take heed therefore to yourselves, and to all the flock, wherein the Holy Spirit has set you as overseers, to shepherd the assembly of God, which he has purchased with the blood of his own.
