Hebrews 3:11

7Therefore, even as the Holy Spirit says, “Today if you will hear his voice,

8don’t harden your hearts as in the rebellion, in the day of the trial in the wilderness,

9where your fathers tested me and tried me, and saw my deeds for forty years.

10Therefore I was displeased with that generation, and said, ‘They always err in their heart, but they didn’t know my ways.’

11As I swore in my wrath, ‘They will not enter into my rest.’”

12Beware, brothers, lest perhaps there might be in any one of you an evil heart of unbelief, in falling away from the living God;

13but exhort one another day by day, so long as it is called “today”, lest any one of you be hardened by the deceitfulness of sin.

14For we have become partakers of Christ, if we hold the beginning of our confidence firm to the end,

15while it is said, “Today if you will hear his voice, don’t harden your hearts, as in the rebellion.”
