That is, "chosen," "selected."
In the Old Testament the word represents derivatives of bachar, elegit;
In the New Testament eklektos. It means properly an object or objects of selection.
This primary meaning sometimes passes into that of "eminent," "valuable," "choice"; often thus as a fact, in places where the King James Version uses "chosen" (or "elect") to translate the original (eg. Isa 42:1; 1Pe 2:6). In the King James Version "elect" (or "chosen") is used of Israel as the race selected for special favor and to be the special vehicle of Divine purposes (so 4 times in Apocrypha, Tobit and Ecclus); of the great Servant of Yahweh (compare Lu 23:35; the "Christ of God, his chosen"); compare eminent saints as Jacob, Moses, Rufus (Ro 16:13); "the lady," and her "sister" of 2 Jn; of the holy angels (1Ti 5:21); with a possible suggestion of the lapse of other angels. Otherwise, and prevalently in the New Testament, it denotes a human community, also described as believers, saints, the Israel of God; regarded as in some sense selected by Him from among men, objects of His special favor, and correspondingly called to special holiness and service.
