God would grant Israel’s desire to have a king, but He set guidelines for the king, guidelines that would complement the nation’s operations and not hinder it from being holy. Moses said, “you shall surely set a king over you whom the LORD your God chooses, one from among your countrymen you shall set as king over yourselves; you may not put a foreigner over yourselves who is not your countryman” (Deut 17:15). God would be the One to select their king, and He did via His prophet, as was the case when Samuel anointed Saul (1 Sam 9:15-16; 15:1), and later David (1 Sam 16:1-3, 12-13). Warren Wiersbe writes:
The king was not to be elected by the people; he was to be chosen by God. Israel’s first king was Saul (1 Sam 9–10), but God never intended Saul to establish a royal dynasty in Israel. Saul was from the tribe of Benjamin, but Judah was the royal tribe (Gen 49:8–10), and the Messiah would come from Judah. Actually, Saul was given to the people to chasten them because they rejected the Lord (1 Sam 8:7), for God’s greatest judgment is to give His people what they want and let them suffer for it.
God knew His people well, and He knew they would be tempted to live in conformity to the pagan values of the world around them. In order to keep His people distinct from other nations, and to keep them looking to Him as their God-King, He placed prohibitions on the kings of Israel. These prohibitions included: 1) multiplying horses to strengthen the army, 2) multiplying wives for pleasure and political alliances, and, 3) greatly increasing silver and gold for financial security.
Starting with the development of the king’s army, God said, “Moreover, he shall not multiply horses for himself, nor shall he cause the people to return to Egypt to multiply horses, since the LORD has said to you, ‘You shall never again return that way’” (Deut 17:16). Horses were used in military battles and pulled chariots, which were the tanks of the day. God wanted the king to look to his Lord for deliverance and not rely on military might like the pagan nations did. Egypt was a major source of horses, and God forbid His people from returning to the place where they’d been delivered from captivity.
Addressing the king’s marital life, God decreed, “He shall not multiply wives for himself, or else his heart will turn away” (Deut 17:17a). Pagan kings in the ancient world multiplied wives as a means of securing political alliances with neighboring nations and also for sexual pleasure, which was the purpose of the concubine. Human relationships either help or hinder a believer’s walk with God, and there was no closer relationship a king could have than with his wife. God knew if Israel’s kings married women with pagan values and practices, it would only be a matter of time before they turned his heart away from Him. Wives played key roles in the lives of Israel’s kings, either for good (Prov 31:10-12) or bad (1 Ki 21:25; 2 Ki 8:16-18).
And concerning the king’s treasury, God said, “nor shall he greatly increase silver and gold for himself” (Deut 17:17b). Having wealth is essential to the economic development of a person and nation, and there was nothing wrong with the king having wealth. This prohibition pertained to the pursuit of wealth by human means, which would prove to be a consuming passion that would turn his heart away from the Lord. David said of God, “Both riches and honor come from You, and You rule over all, and in Your hand is power and might; and it lies in Your hand to make great and to strengthen everyone” (1 Ch 29:12). God may bless His servant with riches; however, David also said, “If riches increase, do not set your heart upon them” (Psa 62:10b). Money was necessary for living, but was also unstable and could easily be lost. The rule was, “Do not weary yourself to gain wealth, cease from your consideration of it. When you set your eyes on it, it is gone. For wealth certainly makes itself wings like an eagle that flies toward the heavens” (Prov 23:4-5; cf., Prov 27:24). The Lord Jesus said, “Beware, and be on your guard against every form of greed; for not even when one has an abundance does his life consist of his possessions” (Luke 12:15). Wisdom is found in the one with a temperate heart (Prov 30:7-9), who is content with what the Lord provides (1 Tim 6:8), is concerned with storing up wealth in heaven (Matt 6:19-21), pursues a life of righteousness (Matt 6:33), and if blessed with wealth, uses it for godly purposes (1 Tim 6:17-19). Daniel Block states:
These prohibitions, then, address three major temptations facing ancient rulers: lust for power, lust for status, and lust for wealth. The text does not prohibit the purchase of horses, or marriage, or the accumulation of some silver and gold. The threefold repetition of “for himself” emphasizes the ban concerning the king’s exploitation of his office for personal gain.
After hand writing a copy of the Law, the king was required to keep its content flowing in the stream of his consciousness at all times. This meant he was to carry the Scriptures with him all the time and read it daily. God said, “It shall be with him and he shall read it all the days of his life, that he may learn to fear the LORD his God, by carefully observing all the words of this law and these statutes” (Deut 17:19). Again, the integrity of language is assumed as subsequent kings would have an objective standard by which to guide their thinking and actions.
The daily reading of God’s Word was also intended to help keep the king humble, “that his heart may not be lifted up above his countrymen and that he may not turn aside from the commandment, to the right or the left, so that he and his sons may continue long in his kingdom in the midst of Israel” (Deut 17:20). The king, like all Israel, was under God’s ultimate authority. But being the king also meant he was to serve as a spiritual leader to God’s people, and this meant he was held to a higher standard, for if the king turned “aside from the commandment, to the right or the left” it meant leading others into sin. But if the king was obedient, both he and his sons would know God’s blessing and the Lord would ensure their continuation in the land. Without question, the most important qualification for the king was to know God’s Word and walk in it. Failure at this point would result in a prideful ruler who would, by default, be governed by the inclinations of his sinful heart and the values and practices of a fallen world that is governed by Satan and his forces.
It is true that David practiced the sin of polygamy contrary to the Law of Moses. From Scripture we know the names of eight of David’s wives: Michal (1 Sam 18:27), Abigail (1 Sam 25:39-42), Ahinoam (1 Sam 25:43), Bathsheba (2 Sam 12:24), Maacah, Haggith, Abital and Eglah (2 Sam 3:2-5). He had other wives and concubines that are not named, as Scripture reveals, “David took more concubines and wives from Jerusalem, after he came from Hebron” (2 Sam 5:13a). Interestingly, the Bible says nothing negative about David’s practice of polygamy, and though it was a sin according to Scripture, it was apparently tolerated in David’s life, perhaps because it never resulted in his wives leading him into idolatry as it did with his son, Solomon (see 1 Kings 11:1-11).
In summary, the Mosaic Law placed limitations on the role of the king in Israel because of the tendency of those in power to become corrupt, because the proclivity of the human heart is bent toward self-interest rather than God’s interests. However, if the king in Israel learned God’s Word and followed His directives, stayed humble and faithful, he and the nation would know ongoing blessing.

 Biblically, some acts of obedience are more important than others, and some acts of sin are more egregious than others. For example, Samuel, told Saul, “Behold, to obey is better than sacrifice” (1 Sam 15:22). Solomon wrote, “To do righteousness and justice is desired by the LORD more than sacrifice” (Pro 21:3). Jesus told the scribes and Pharisees, “you tithe mint and dill and cummin, and have neglected the weightier provisions of the law: justice and mercy and faithfulness” (Matt 23:23). Likewise, some sins are worse than others and bring greater judgment. Jesus told His disciples not to be like the Scribes, “who devour widows’ houses, and for appearance’s sake offer long prayers”, saying, “These will receive greater condemnation” (Luke 20:47). Concerning the citizens of Chorazin and Bethsaida, Jesus said, “it will be more tolerable for Tyre and Sidon in the day of judgment than for you” (Matt 11:22). The apostle John, writing to believers, states, “All unrighteousness is sin” (1 John 5:17a). However, he drew a distinction, saying, “there is a sin that results in death” (1 John 5:16b), and “there is a sin that does not result in death” (1 John 5:17b). These are obvious statements that show some acts of obedience are better than others, and some acts of sin are worse than others.
