6 Seeing then that the promise remains over [from past times] for some to enter that rest, and that those who formerly were given the good news about it and the opportunity, failed to appropriate it and did not enter because of disobedience,
7 Again He sets a definite day, [a new] Today, [and gives another opportunity of securing that rest] saying through David after so long a time in the words already quoted, Today, if you would hear His voice and when you hear it, do not harden your hearts.
8 [This mention of a rest was not a reference to their entering into Canaan.] For if Joshua had given them rest, He [God] would not speak afterward about another day.
9 So then, there is still awaiting a full and complete Sabbath-rest reserved for the [true] people of God;
10 For he who has once entered [God’s] rest also has ceased from [the weariness and pain] of human labors, just as God rested from those labors peculiarly His own.
11 Let us therefore be zealous and exert ourselves and strive diligently to enter that rest [of God, to know and experience it for ourselves], that no one may fall or perish by the same kind of unbelief and disobedience [into which those in the wilderness fell].Hebrews 4:6-11 (AMPC)
