Hebrews 3:7-19 - A Serious Warning Against Unbelief

⁷ So, even as the Holy Spirit said [Psa. 95:7-11], "Today, if you hear His [i.e., God's] voice, ⁸ do not have a stubborn heart like you did when you provoked [God] during the time you tested [His patience] in the desert, ⁹ where your forefathers tried me and tested [my patience] when they saw what I did for forty years. ¹⁰ Therefore, I was angry with that generation of people and said, 'They always go astray in their hearts, and they did not understand my ways.' ¹¹ So I vowed in my anger, 'They will not enter a state of rest with me.'"

¹² Pay attention, brothers, so that there will not be in any one of you an evil heart of unbelief, [resulting] in falling away from the living God. ¹³ But [instead], encourage one another each day, as long as it is [still] called "Today," so that none of you becomes stubborn [as a result] of the deceitfulness of sin. ¹⁴ For we have become sharers with Christ, if we hold firmly onto the confidence [we had in Him] from the beginning until the end [of our lives]. ¹⁵ As it has been said [Psa. 95:7], "Today, if you hear His [i.e., God's] voice, do not have a stubborn heart like you did when you provoked [God]."

¹⁶ For who were they who heard [God] and provoked [Him]? Was it not everyone who was led out of Egypt by Moses? ¹⁷ And who was God angry with for forty years? Was it not with those people who sinned, whose bodies fell [dead] in the desert? ¹⁸ And to whom did God vow that they would not enter a state of rest with Him? [Was it not] those who were disobedient to Him? ¹⁹ And [so] we see that they were not able to enter [a state of rest with God] because of [their] unbelief.
