properly, "to envelop in" (en, "in," duno, "to enter"), "to put on," as of a garment, has the secondary and intransitive significance of "creeping into, insinuating oneself into," and is found with this meaning in 2Ti 3:6. Cp. enduo, "to clothe."
"to enter in by the side" (para, "beside," eis, "in"), to insinuate oneself into, by stealth, to creep in stealthily, is used in Jud 1:4. signifies a "creeping thing" (herpo, "to creep;" Eng., "serpent" is from the same root), Jam 3:7 (RV, "creeping things," for AV, "serpents," which form only one of this genus); it is set in contrast to quadrupeds and birds, Act 10:12, Act 11:6, Rom 1:23. See SERPENT.
