In some forms, it is the same as apaomai, which means to "pray to," or "pray for." -- "Shall be taken" is one of Christ's favorite "multiple meaning" words. It is a verb that means "to raise up," "elevate," "to bear," "to carry off," "to take and apply to any use," "lifted" in the sense of "removed," and "to cause to cease." Jesus uses this verb to refer to what will happen to "the son of man," which can apply either to his being raised from the dead or lifted up on the cross.
