C. F. Keil and Franz Delitzsch on Leviticus 18:24-30

Lev 18:24-30

In the concluding exhortation God pointed expressly to the fact, that the nations which He was driving out before the Israelites (the participle משׁלּח is used of that which is certainly and speedily coming to pass) had defiled the land by such abominations as those, that He had visited their iniquity and the land had spat out its inhabitants, and warned the Israelites to beware of these abominations, that the land might not spit them out as it had the Canaanites before them. The pret. ותּקא (Lev 18:25) and קאה (Lev 18:28) are prophetic (cf. Lev 20:22-23), and the expression is poetical. The land is personified as a living creature, which violently rejects food that it dislikes. “Hoc enim tropo vult significare Scriptura enormitatem criminum, quod scilicet ipsae creaturae irrationales suo creatori semper obedientes et pro illo pugnantes detestentur peccatores tales eosque terra quasi evomat, cum illi expelluntur ab ea” (C. a Lap.).
