8 Do not harden your hearts, as [happened] in the rebellion [of Israel] and their provocation and embitterment [of Me] in the day of testing in the wilderness,
9 Where your fathers tried [My patience] and tested [My forbearance] and found I stood their test, and they saw My works for forty years.
10 And so I was provoked (displeased and sorely grieved) with that generation, and said, They always err and are led astray in their hearts, and they have not perceived or recognized My ways and become progressively better and more experimentally and intimately acquainted with them.
11 Accordingly, I swore in My wrath and indignation, They shall not enter into My rest. [Ps. 95:7-11.]
12 [Therefore beware] brethren, take care, lest there be in any one of you a wicked, unbelieving heart [which refuses to cleave to, trust in, and rely on Him], leading you to turn away and desert or stand aloof from the living God.
13 But instead warn (admonish, urge, and encourage) one another every day, as long as it is called Today, that none of you may be hardened [into settled rebellion] by the deceitfulness of sin [by the fraudulence, the stratagem, the trickery which the delusive glamor of his sin may play on him].
14 For we have become fellows with Christ (the Messiah) and share in all He has for us, if only we hold our first newborn confidence and original assured expectation [in virtue of which we are believers] firm and unshaken to the end.
