Hebrews 3:7-19 - A Serious Warning Against Unbelief

⁷ Therefore, as the Holy Spirit says-- 'If to-day you hear God's voice, ⁸ Harden not your hearts, as when Israel provoked me on the day when they tried my patience in the desert, ⁹ Where your ancestors tried my forbearance, And saw my mighty deeds for forty years. ¹⁰ Therefore I was sorely vexed with that generation, And I said-- "Their hearts are always straying; They have never learned my ways"; ¹¹ While in my wrath I swore-- "They shall never enter upon my Rest."'

¹² Be careful, Brothers, that there is never found in any one of you a wicked and faithless heart, shown by his separating himself from the Living God. ¹³ Rather encourage one another daily--while there is a 'To-day'--to prevent any one among you from being hardened by the deceitfulness of Sin. ¹⁴ For we now all share in the Christ, if indeed we retain, unshaken to the end, the confidence that we had at the first. ¹⁵ To use the words of Scripture-- 'If to-day you hear God's voice, harden not your hearts, as when Israel provoked me.'

¹⁶ Who were they who heard God speak and yet provoked him? Were not they all those who left Egypt under the leadership of Moses? ¹⁷ And with whom was it that God was sorely vexed for forty years? Was not it with those who had sinned, and who fell dead in the desert? ¹⁸ And who were they to whom God swore that they should not enter upon his rest, if not those who had proved faithless? ¹⁹ We see, then, that they failed to enter upon it because of their want of faith.
