Decay

"to make old" (palaios), is translated in Heb 8:13, firstly, "hath made ... old," secondly (Passive Voice), RV "is becoming old" (AV, "decayeth"); "wax old," Luk 12:33, Heb 1:11. See OLD.

"to destroy utterly," as used in 2Co 4:16 (here in the Passive Voice, lit., "is being destroyed), is rendered "is decaying" (RV, for AV, "perish"). See CORRUPT, DESTROY.
