The passage may appear to directly equate obedience and submission together, but each word conveys a separate and distinct concept. Although today's passage includes both obedience and submission, it is important to recognize that these two words involve separate acts. Earlier studies noted a twofold definition of obedience: first, having an attentive ear, followed by acting upon what has been said. Dividing submission into two parts helps to better understand it too (sub + mission). The prefix sub means under (thus a submarine travels under the water), and the root word mission means to be sent out. Obedience, therefore, emphasizes the act of hearing and doing, while submission emphasizes the act of placing oneself under the authority of another.
The Lord blessed the throne of David and desired to do the same for his posterity. Because the Lord wanted to establish Solomon’s rule, He provided some guidelines for Solomon. One prominent issue involved Solomon following in his father’s footsteps by living with integrity of heart. Integrity is very much a matter of the heart. In fact, four times in scripture integrity is associated with the heart. Twice the Bible refers to the integrity of Abimelech’s heart (Genesis 20:5-6) and another two times it refers to the integrity of David’s heart (1 Kings 9:4; Psalm 78:72). Though these men had little else in common, both understood that integrity involved a matter of the heart. A lack of integrity is first and foremost a heart issue.
