Hebrews 3:7-11; Hebrews 3:15

7 Therefore, as the Holy Spirit says, "Today, if you hear his voice,

8 do not harden your hearts as in the rebellion, on the day of testing in the wilderness,

9 where your fathers put me to the test and saw my works for forty years.

10 Therefore I was provoked with that generation, and said, 'They always go astray in their heart; they have not known my ways.'

11 As I swore in my wrath, 'They shall not enter my rest.'"

15 As it is said, "Today, if you hear his voice, do not harden your hearts as in the rebellion."
