Equal unto the angels (isaggeloi). A rare and late word from iso, equal, and aggelo. Only here in the N.T. Mark and Matthew have "as angels" (w aggeloi). Angels do not marry, there is no marriage in heaven. Sons of God, being sons of the resurrection (uioi qeou th anastasew uioi onte). This Hebraistic phrase, "sons of the resurrection" defines "sons of God" and is a direct answer to the Sadducees.
