Hebrews 4:6
KJV
Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:
NIV
Therefore since it still remains for some to enter that rest, and since those who formerly had the good news proclaimed to them did not go in because of their disobedience,
The key difference between “unbelief” and “disobedience” in this passage is that unbelief is a matter of God judging the heart, whereas disobedience is a matter of God judging the works. See also: Rom. 11:32, Heb. 3:18, Heb. 4:11
