Keil & Delitzsch, on Judg 14:8

When some time had elapsed after the betrothal, he came again to fetch her (take her home, marry her), accompanied, as we learn from Jdg 14:9, by his parents. On the way "he turned aside (from the road) to see the carcase of the lion; and behold a swarm of bees was in the body of the lion, also honey." The word מפּלת, which only occurs here, is derived from נפל, like πτῶμα from πίπτω, and is synonymous with נבלה, cadaver, and signifies not the mere skeleton, as bees would not form their hive in such a place, but the carcase of the lion, which had been thoroughly dried up by the heat of the sun, without passing into a state of putrefaction. "In the desert of Arabia the heat of a sultry season will often dry up all the moisture of men or camels that have fallen dead, within twenty-four hours of their decease, without their passing into a state of decomposition and putrefaction, so that they remain for a long time like mummies, without change and without stench" (Rosenmller, Bibl. Althk. iv. 2, p. 424). In a carcase dried up in this way, a swarm of bees might form their hive, just as well as in the hollow trunks of trees, or clefts in the rock, or where wild bees are accustomed to form them, notwithstanding the fact that bees avoid both dead bodies and carrion (see Bochart, Hieroz, ed. Ros. iii. p. 355).
