Ye rejoice (καυχᾶσθε)

Rev., glory. See on James 2:13.

Boastings (ἀλαζονείαις)

Only here and 1 John 2:16. The kindred word ἀλαζών, a boaster, is derived from ἄλη, 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 ἀλαζονεία 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.
