Adam Clarke on Numbers 21:27

They that speak in proverbs - המשלים hammoshelim, from משל mashal, to rule, to exercise authority; hence a weighty proverbial saying, because admitted as an axiom for the government of life.

The ode from the 27th to the 30th verse is composed of three parts. The first takes in Num 21:27 and Num 21:28; the second Num 21:29; and the third Num 21:30.

The first records with bitter irony the late insults of Sihon and his subjects over the conquered Moabites.

The second expresses the compassion of the Israelites over the desolations of Moab, with a bitter sarcasm against their god Chemosh, who had abandoned his votaries in their distress, or was not able to rescue them out of the hands of their enemies.
