Ibrani 4:9

4:9 Consequently a Sabbath rest remains for the people of God.

Ibrani 9:18

9:18 So even the first covenant was inaugurated with blood. ¹ 

[9:18]  ¹ sn The Greek text reinforces this by negating the opposite (“not even the first covenant was inaugurated without blood”), but this double negation is not used in contemporary English.
