C. F. Keil and Franz Delitzsch on 2 Samuel 14:17

2Sa 14:17 “Then thine handmaid thought, may the word of my lord the king be for rest (i.e., tend to give me rest);for as the angel of God (the angel of the covenant, the mediator of the blessings of divine grace to the covenant-nation), so is my lord the king to hear good and evil (i.e., listening to every just complaint on the part of his subjects, and granting help to the oppressed),and Jehovah thy God be with thee!”
