{Are to perish with the using} (estin eis phthoran t(8869)
apochr(8873)ei). Literally, "are for perishing in the using."
Phthora (from phtheir(935c)) is old word for decay, decomposition.
Apochr(8873)is (from apochraomai, to use to the full, to use up),
late and rare word (in Plutarch), here only in N.T. Either
locative case here or instrumental. These material things all
perish in the use of them.
