I will execute judgments upon Moab,.... For though the Chaldeans and Arabians were the instruments of their ruin, their destruction was of the Lord; it was his hand that was upon them, and his vengeance that was executed on them, for their hard sayings against his people; for though he had spoke against them in his providence, and chastised them for their sins, yet he will not suffer others to speak against them:
and they shall know that I am the Lord; that takes part with Judah, and will avenge himself of all their enemies.
