James 4:16

Ye rejoice [κ α υ χ α σ θ ε]. Rev., glory. See on ch. James 2:13.

Boastings [α λ α ζ ο ν ε ι α ι ς]. Only here and 1 John 2:16. The kindred word ajlazwn a boaster, is derived from alh, a wandering or roaming; hence, primarily, a vagabond, a quack, a mountebank. From the empty boasts of such concerning the cures and wonders they could perform, the word passed into the sense of boaster. One may boast truthfully; but ajlazoneia, is false and swaggering boasting. Rev. renders vauntings, and rightly, since vaunt is from the Latin vanus, empty, and therefore expresses idle or vain boasting.
