Thus God rendered the wickedness of Abimelech which he did
unto his father
To the disgrace of his father's character, and to the hurt of his father's family:
in slaying his seventy brethren;
excepting one, which was a piece of unheard of wickedness, attended with most sad aggravations; the shedding such blood required blood to be shed again, and it was righteous judgment God rendered to him; this, and the following verse contain the remarks made upon this history by the writer of it, who, as we have seen, in all probability, was the Prophet Samuel.
