Numbers 35:19-21

Young's Literal Translation

¹⁹ `The redeemer of blood himself doth put the murderer to death; in his coming against him he doth put him to death.

²⁰ `And if in hatred he thrust him through, or hath cast [anything] at him by lying in wait, and he dieth;

²¹ or in enmity he hath smitten him with his hand, and he dieth; the smiter is certainly put to death; he [is] a murderer; the redeemer of blood doth put the murderer to death in his coming against him.
