'Angel' in the Bible

"So your humble servant is saying, "Please, your majesty, let what the king has to say be of comfort, because just as the angel of God is, so also is your majesty the king to discern both good and evil. And may the LORD your God remain present with you.'"

"As your soul lives, your majesty, the king," the woman answered, "no one can divert anything left or right from what your majesty the king has spoken! As a matter of fact, it was your servant Joab! He was there, giving me precise orders about everything that your humble servant was to say. Your servant Joab did this, intending to change the outcome of this matter. Nevertheless, your majesty is wise, like the wisdom of the angel of God, to be aware of everything that's going on throughout the earth."
