Passage
For he has said somewhere of the seventh [day] thus, And God rested on the seventh day from all his works:
For he has said somewhere of the seventh [day] thus, And God rested on the seventh day from all his works:
Hebrews 4:2 For indeed we have had glad tidings presented to us, even as they also; but the word of the report did not profit *them*, not being mixed with faith in those who heard.
Hebrews 4:3 For we enter into the rest who have believed; as he said, As I have sworn in my wrath, If they shall enter into my rest; although the works had been completed from [the] foundation of [the] world.
Hebrews 4:4 For he has said somewhere of the seventh [day] thus, And God rested on the seventh day from all his works:
Hebrews 4:5 and in this again, If they shall enter into my rest.
Hebrews 4:6 Seeing therefore it remains that some enter into it, and those who first received the glad tidings did not enter in on account of not hearkening to the word,
The verse centers on "said", "somewhere", "seventh", "thus", "rested", and "works". It is saying that the verse draws attention to "said" and "somewhere", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "For we enter into the rest who..." into verse 5's "and in this again If they shall...", so "said" and "somewhere" 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 "said" and "somewhere" with trust shaped by these words, not by a vague optimism outside the passage.
