Hebrews 3:7-14
7 That is why, as the Holy Spirit says: If only you would listen to him today!
8 Do not harden your hearts, as at the rebellion, as at the time of testing in the desert,
9 when your ancestors challenged me, and put me to the test, and saw what I could do
10 for forty years. That was why that generation sickened me and I said, 'Always fickle hearts, that cannot grasp my ways!'
11 And then in my anger I swore that they would never enter my place of rest.
12 Take care, brothers, that none of you ever has a wicked heart, so unbelieving as to turn away from the living God.
13 Every day, as long as this today lasts, keep encouraging one another so that none of you is hardened by the lure of sin,
14 because we have been granted a share with Christ only if we keep the grasp of our first confidence firm to the end.
