'Chosen One' in the Bible

O Lord God, do not reject your chosen ones! Remember the faithful promises you made to your servant David!"

And Amaziah gathereth Judah, and appointeth them, according to the house of the fathers, for heads of the thousands, and for heads of the hundreds, for all Judah and Benjamin; and he inspecteth them from a son of twenty years and upward, and findeth them three hundred thousand chosen ones, going forth to the host, holding spear and target.

And He causeth to go up against them the king of the Chaldeans, and he slayeth their chosen ones by the sword in the house of their sanctuary, and hath had no pity on young man and virgin, old man and very aged -- the whole He hath given into his hand.
