'Angel of God' in the Bible

Your servant also thought, 'May the word of my lord the king {bring rest}, for as an angel of God, so [is] my lord the king, {to sense what is good and what is bad}.' May Yahweh your God be with you."

In order {to change the situation}, your servant Joab did this thing. But my lord [has] wisdom, as the wisdom of an angel of God, to know all that [is] on the earth."

But he slandered against your servant to my lord the king. My lord the king [is] like the angel of God; {do as you see fit.}."
