Hebrews 9:18

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

Hebrews 12:4

12:4 You have not yet resisted to the point of bloodshed ²  in your struggle against sin.

[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.

[12:4]  ² tn Grk “until blood.”
