• Hebrews 3:7-13
  Therefore, as the Holy Spirit says:
  “ Today, if you will hear His voice,
  Do not harden your hearts as in the rebellion,
  In the day of trial in the wilderness,
  Where your fathers tested Me, tried Me,
  And saw My works forty years.
  Therefore I was angry with that generation,
  And said, ‘They always go astray in their heart,
  And they have not known My ways.’
  So I swore in My wrath,
  'They shall not enter My rest.'"
  Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God; but exhort one another daily, while it is called "Today," lest any of you be hardened through the deceitfulness of sin.

  “Do not harden your hearts, as in the rebellion,
  As in the day of trial in the wilderness,
  When your fathers tested Me;
  They tried Me, though they saw My work.
  For forty years I was grieved with that generation,
  And said, ‘It is a people who go astray in their hearts,
  And they do not know My ways.’
