C. F. Keil and Franz Delitzsch on Deuteronomy 14:3-21

Deu 14:3-21

With reference to food, the Israelites were to eat nothing whatever that was abominable. In explanation of this prohibition, the laws of Lev 11 relating to clean and unclean animals are repeated in all essential points in vv. 4-20 (for the exposition, see at Lev 11); ); also in Deu 14:21 the prohibition against eating any animal that had fallen down dead (as in Exo 32:30 and Lev 17:15), and against boiling a kid in its mother’s milk (as in Exo 23:19).
