Bible Notes Online - 1-Samuel 8 - ESV
Commentary

v1-3: Samuel's sons became like Eli's sons. Perhaps Samuel was at fault for not properly restraining them, like Eli before him, and David after him. Samuel's sons were judges, not priests. There is also a pattern here of children not following their father's example.

v4-6: The unfaithfulness of Samuel's sons, and the imminent death of Samuel, made the people, and especially the leaders, consider their future.

Their conclusion was "appoint a king to lead us"; but they wanted to do what the other nations did. It is a serious mistake to copy the example of unbelievers; the ungodly cannot be expected to set a godly example; political and business leaders do not generally promote godly principles; scientists and educationalists to not promote godly obedience. We are not surprised that their request displeased Samuel.

It seems that Samuel walked so close to the Lord that he instinctively knew what would and what would not please the Lord. That was the result of many, many hours spent on the presence of God.

v7: In asking for a king, the people rejected God's authority over them. They should rather have looked to the Lord God to raise up leaders for them, as in Judg 2.18; 3.10, 15. Yet, in His mercy the Lord turns their second best into His best Messianic plan.

v8-9: Samuel had the task of explaining to the people the behaviour of a king, especially that he would become a burden to the people. Later, wise men suggested to Rehoboam that he be a servant to the people (1 Kings 12.7), but he rejected that advice.

v10-18: Samuel described the burden that the king would be. This is the equivalent of civil servants, military personnel, and taxation, with which a government will burden a society. In prophecy, Samuel said that, as a result of this burden, the people would cry out to God.

v19: The people were set on their decision, and would not be moved.

v20: They wanted a king, to fight their battles, and to make their decisions; they wanted to avoid personal responsibility. They were right to criticise Samuel's sons, but they refused to accept that there was another alternative.

v21-22: The people had rejected Samuel's wise counsel. The Lord God granted their request; Ps 106.15; they would have to bear the consequences of their desires.
