Judg 9:24

לָב֕וֹא חֲמַ֖ס שִׁבְעִ֣ים בְּנֵֽי־יְרֻבָּ֑עַל וְדָמָ֗ם לָשׂ֞וּם עַל־אֲבִימֶ֤לֶךְ אֲחִיהֶם֙ אֲשֶׁ֣ר הָרַ֣ג אוֹתָ֔ם וְעַל֙ בַּעֲלֵ֣י שְׁכֶ֔ם אֲשֶׁר־חִזְּק֥וּ אֶת־יָדָ֖יו לַהֲרֹ֥ג אֶת־אֶחָֽיו׃

in order that the crime against the seventy sons of Jerubbaal might come to justice and their blood be avenged on their brother Abimelech and on the leaders of Shechem, who had helped him murder his brothers.
