Imamat 11:44

11:44 for I am the Lord your God and you are to sanctify yourselves and be holy because I am holy. You must not defile yourselves by any of the swarming things that creep on the ground,

Imamat 20:25

20:25 Therefore you must distinguish ¹  between the clean animal and the unclean, and between the unclean bird and the clean, and you must not make yourselves detestable by means of an animal or bird or anything that creeps on the ground – creatures ²  I have distinguished for you as unclean. ³ 

[20:25]  ¹ tn Heb “And you shall distinguish.” The verb is the same as “set apart” at the end of the previous verse. The fact that God had “set them apart” from the other peoples roundabout them called for them to “distinguish between” the clean and the unclean, etc.

[20:25]  ² tn The word “creatures” has been supplied in the translation to make it clear that the following relative clause modifies the animal, bird, or creeping thing mentioned earlier, and not the ground itself.

[20:25]  ³ tc The MT has “to defile,” but Smr, LXX, and Syriac have “to uncleanness.”
