Ulangan 19:13

19:13 You must not pity him, but purge out the blood of the innocent ¹  from Israel, so that it may go well with you.

Ulangan 22:7

22:7 You must be sure ²  to let the mother go, but you may take the young for yourself. Do this so that it may go well with you and you may have a long life.

[19:13]  ¹ sn Purge out the blood of the innocent. Because of the corporate nature of Israel’s community life, the whole community shared in the guilt of unavenged murder unless and until vengeance occurred. Only this would restore spiritual and moral equilibrium (Num 35:33).

[22:7]  ² tn The Hebrew text uses the infinitive absolute for emphasis, which the translation seeks to reflect with “be sure.”
