בַּלַּ֣ע אֲ֭דֹנָי פַּלַּ֣ג לְשׁוֹנָ֑ם כִּֽי־רָאִ֨יתִי חָמָ֖ס וְרִ֣יב בָּעִֽיר׃
主啊,求你毀滅他們,使他們的言語分歧;因為我在城中看見了強暴和紛爭。
Rashi
divide their tongue Divide it so that no one should pay them heed. And Menachem (p. 142) interpreted פלג as an expression of division.
Rashi
Destroy (Defey or defay in Old French, destroy, defais in modern French,) like (Lam. 2:8): “He did not restrain his hand from destroying (מבלע).” So did Menachem interpret it [p. 46].
