By reason of transgression, i.e. either the transgression of the priests, for Jason perfidiously took away the priesthood from his brother Onias, and afterwards Menelaus did the like by him. Or else for the sin of the people about the worship of God. Or else Antiochus wickedly and in contempt of God put soldiers into the city to hinder or break up the meetings of God's people about his worship, /APC 1Ma 1:47. It cast down the truth, i.e. the law of God, called the law of truth, Zechariah 2:6, which Antiochus cut in pieces and burnt, /APC 1Ma 1:59. This was his practice, and it succeeded for a time as he desired.
