'Angel' in the Bible

Then your servant said, May the word of my lord the king give me peace! for my lord the king is as the angel of God in his hearing of good and bad: and may the Lord your God be with you!

This he did, hoping that the face of this business might be changed: and my lord is wise, with the wisdom of the angel of God, having knowledge of everything on earth.

He has given you a false account of me: but my lord the king is like the angel of God: do then whatever seems good to you.

And when the hand of the angel was stretched out in the direction of Jerusalem, for its destruction, the Lord had regret for the evil, and said to the angel who was sending destruction on the people, It is enough; do no more. And the angel of the Lord was by the grain-floor of Araunah the Jebusite.

And when David saw the angel who was causing the destruction of the people, he said to the Lord, Truly, the sin is mine; I have done wrong: but these are only sheep; what have they done? let your hand be against me and against my family.
