Commentary for Zechariah 11:10

And I took My [first] staff, [called] Pleasantness I broke the power of the kings of Israel in the days of Jehoahaz the son of Jehu - to the extent that the king of Aram destroyed them and made them like dust to trample (II Kings 13:7) - and in the days of Hoshea the son of Elah, when I delivered them into the hands of Sennacherib and he exiled them (ibid. 17:6).

to nullify My covenant that I [had] formed with all the peoples To show them that because they betrayed Me, I nullified My covenant that I formed with all the peoples concerning them, that the [peoples] not harm them. For, on that condition I gave them the Torah, that if they keep it, they will be free from the kingdoms; that no nation or tongue shall rule over them. And do not be surprised if Scripture speaks of their salvation from the hands of the enemy as forming a covenant with the enemy, for we find a similar verse (Hosea 2:20): “And I will make a covenant for them on that day with the beasts of the field, etc.”
