Passage
and in this [place] again, They shall not enter into my rest.
and in this [place] again, They shall not enter into my rest.
Hebrews 4:3 For we who have believed do enter into that rest; even as he hath said, As I sware in my wrath, They shall not enter into my rest: although the works were finished from the foundation of the world.
Hebrews 4:4 For he hath said somewhere of the seventh [day] on this wise, And God rested on the seventh day from all his works;
Hebrews 4:5 and in this [place] again, They shall not enter into my rest.
Hebrews 4:6 Seeing therefore it remaineth that some should enter thereinto, and they to whom the good tidings were before preached failed to enter in because of disobedience,
Hebrews 4:7 he again defineth a certain day, To-day, saying in David so long a time afterward (even as hath been said before), To-day if ye shall hear his voice, Harden not your hearts.
The verse centers on "place", "again", "shall", "enter", and "rest". It is saying that the verse draws attention to "place" and "again", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "For he hath said somewhere of the..." into verse 6's "Seeing therefore it remaineth that some should...", so "place" and "again" belong inside that flow. In Hebrews context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "place" and "again" with trust shaped by these words, not by a vague optimism outside the passage.
