 Herod's attempt to humiliate Alexander by restoring to honor Antipater, an older son by another wife, resulted disastrously.Antipater's insidious plotting and the open enmity to Herod shown by Alexander widened the breach between father and son to such an extent that in the year 12 BC, Herod felt himself constrained to bring charges against his sons before Augustus.A reconciliation was brought about, but it was of short duration; and shortly afterward (about 10 BC) Alexander was thrown into prison upon the evidence of a tortured witness who accused him of planning the murder of Herod.
