Did Abimelech sacrifice his 70 brothers on an altar?

[tonychanyt]

Gideon destroyed Baal's altar in Judges 6:

25 That same night the LORD said to him, "Take the second bull from your father's herd, the one seven years old. Tear down your father's altar to Baal and cut down the Asherah pole beside it.

Judges 8:

30 Gideon had seventy sons of his own, since he had many wives. 31 His concubine, who dwelt in Shechem, also bore him a son, and he named him Abimelech.

Then, Gideon died.

Judges 9:

5a he [Abimelech] went to his father’s house in Ophrah and killed his brothers the sons of Jerubbaal [i.e., Gideon], seventy men, on one stone.

Did Abimelech sacrifice his brothers?

Probably, according to Jamieson-Fausset-Brown:

Abimelech slew his brethren on one stone, either by dashing them from one rock, or sacrificing them on one stone altar, in revenge for the demolition of Baal's altar by their father. This latter view is the more probable, from the Shechemites (Jud 9:24) aiding in it.

Abimelech sacrificed Gideon's 70 sons on one stone block in an altar to Baal. Unlike his father, Gideon, Abimelech served Baal. The murders were done with the help of the citizens of Shechem.

Judges 9:

22 After Abimelek had governed Israel three years, 23 God stirred up animosity between Abimelek and the citizens of Shechem so that they acted treacherously against Abimelek. 24 God did this in order that the crime against Jerub-Baal’s seventy sons, the shedding of their blood, might be avenged on their brother Abimelek and on the citizens of Shechem, who had helped him murder his brothers.
