In Hebrews chapter 4, the author continues his reasoning...

Chapter 3 (‘Yesterday’): They Refused to Trust God for Earthly Rest thru Moses

Chapter 4 (‘Today’): Do Not Fail to Trust God for Eternal Rest in Jesus!

The promised land & the Sabbath day sign were just shadows, foreshadowing God’s ultimate, eternal rest that Jesus brings.
