Glossa Ordinaria

(non occ.) Or it may be said, that the word that does not here denote the cause; for the prophecy was not fulfilled merely because it was to be fulfilled. But it is put consecutively, as in Genesis, He hung the other on the gallows, that the truth of the interpreter might be proved; (Gen. 40:22.) since by the weighing of one, truth is established. So also in this place we must understand it as if it were, that which was foretold being done, the prophecy was accomplished.
