The King James Bible addresses obedience in several passages:
1 Samuel 15:22 (KJV)
22 And Samuel said, Hath the LORD as great delight in burnt offerings and sacrifices, as in obeying the voice of the LORD? Behold, to obey is better than sacrifice, and to hearken than the fat of rams.
John 14:15 (KJV)
15 If ye love me, keep my commandments.
Deuteronomy 28:1-2 (KJV)
1 And it shall come to pass, if thou shalt hearken diligently unto the voice of the LORD thy God, to observe and to do all his commandments which I command thee this day, that the LORD thy God will set thee on high above all nations of the earth: 2 And all these blessings shall come on thee, and overtake thee, if thou shalt hearken unto the voice of the LORD thy God.
James 1:22 (KJV)
22 But be ye doers of the word, and not hearers only, deceiving your own selves.
Acts 5:29 (KJV)
29 Then Peter and the other apostles answered and said, We ought to obey God rather than men.
