And the LORD said to Samuel, “Listen to the voice of the people in all that they say to you. For it is not you they have rejected, but they have rejected Me as their king.
The LORD tells Samuel to listen, because the people are rejecting Him as king rather than rejecting Samuel alone.
It gives the request its deepest meaning.
1When Samuel grew old, he appointed his sons as judges over Israel. 2The name of his firstborn son was Joel, and the name of his second was Abijah. They were judges in Beersheba. 3But his sons did not walk in his ways; they turned aside toward dishonest gain, accepting bribes and perverting justice. 4So all the elders of Israel gathered together and came to Samuel at Ramah. 5“Look,” they said, “you are old, and your sons do not walk in your ways. Now appoint a king to judge us like all the other nations.” 6But when they said, “Give us a king to judge us,” their demand was displeasing in the sight of Samuel; so he prayed to the LORD. 7And the LORD said to Samuel, “Listen to the voice of the people in all that they say to you. For it is not you they have rejected, but they have rejected Me as their king. 8Just as they have done from the day I brought them up out of Egypt until this day, forsaking Me and serving other gods, so they are doing to you. 9Now listen to their voice; but you must solemnly warn them and show them the manner of the king who will reign over them.”
