A — 1: παράπτωμα
(Strong's #3900 — Noun Neuter — paraptoma — par-ap'-to-mah )

primarily "a false step, a blunder" (akin to parapipto, "to fall away," Hebrews 6:6 ), lit., "a fall beside," used ethically, denotes "a trespass," a deviation, from uprightness and truth, Matthew 6:14,15 (twice); 18:35, in some mss.; Mark 11:25,26; in Romans the RV substitutes "trespass" and "trespasses" for AV, "offense" and "offenses," Romans 4:25 , "for (i.e., because of) our trespasses;" Romans 5:15 (twice), where the trespass is that of Adam (in contrast to the free gift of righteousness, ver. 17, a contrast in the nature and the effects); Romans 5:16 , where "of many trespasses" expresses a contrast of quantity; the condemnation resulted from one "trespass," the free gift is "of (ek, expressing the origin, and throwing stress upon God's justifying grace in Christ) many trespasses;" Romans 5:17 , introducing contrast between legal effects and those of Divine grace; Romans 5:18 , where the RV, "through one trepass," is contrasted with "one act of righteousness;" this is important, the difference is not between one man's "trespass" and Christ's righteousness (as AV), but between two acts, that of Adam's "trespass" and the vicarious death of Christ; Romans 5:20 [(cp. TRANSGRESSION, B, No. 1 (d)]; in 2—Corinthians 5:19 , AV and RV, "trespasses;" in Ephesians 1:7 , RV, "trespasses" (AV, "sins"); in Ephesians 2:1 , RV, "(dead through your) trespasses," AV, "(dead in) trespasses;" Ephesians 2:5 , RV, "(dead through our) trespasses," AV, "(dead in) sins;" so Colossians 2:13 (1st part); in the 2nd part, AV and RV, "trespasses."
