over and above: what goes past the ordinary measure, whether as an extra one side has that another does not or as a supply beyond what is needed
The picture behind the word is a line, and a quantity that runs past it. In ordinary Greek this was business language: the surplus in the accounts, the money still there once the bills are paid, the stock nobody needs. It could also describe a person who stood out from the ordinary run of people.
The New Testament uses this side of the word in three ways:
- as something one side has that the other does not, which is why Paul can ask what advantage the Jew has over the Gentile
- as conduct that goes further than anyone would expect, since greeting only your own friends is no more than what everybody already does
- as a supply that keeps coming after the need has been met, which is the promise that the sheep will have life and something more besides
None of this is special religious vocabulary. It is the plain arithmetic of "there is extra," and the same everyday word stands behind the verb for overflowing (περισσεύω) and the noun for a surplus (περισσεία).
Nuances
Whether περισσόν in John 10:10 denotes a quantitative surplus (a greater amount of life, or of what sustains life) or a qualitatively superior kind of life.
- contestedQuantitative. The lexica parse περισσὸν ἔχειν as to have a surplus or an abundance, citing Xenophon (Anabasis 7.6.31; Oeconomicus 20.1); the Expositor's Greek Testament adds that the surplus is more probably an abundance of all that sustains life, and that the repetition of ἔχωσιν gives the second element independent standing, which favours reading περισσόν as a coordinated object rather than an adverbial accusative. The Syriac renders it as something more abundant.; BDAG, s.v. περισσός; LSJ, s.v. περισσός (Attic περιττός); M. Dods, "The Gospel of St. John," in The Expositor's Greek Testament, vol. 1
- contestedQualitative in emphasis. Because ζωή in this Gospel is characteristically the eschatological life of God, the more that is promised is a superior kind of life rather than merely a larger quantity of it. Commentators reading this way also reject any prosperity construal of the verse.; C. S. Keener, The Gospel of John: A Commentary, vol. 1
