Verse 20. - He shall snatch; rather, one shall devour. A man, i.e., shall plunder and ravage in one quarter, and yet not be satisfied; then he shall do the same in another, and still desire more. "Increase of appetite shall grow by what it feeds on." There shall be no sense of satiety anywhere. The flesh of his own arm. In a civil war, or a time of anarchy, each man is always "eating the flesh of his own arm" - i.e. injuring his neighbor, who is his own natural protector and defender.

9:8-21 Those are ripening apace for ruin, whose hearts are unhumbled under humbling providences. For that which God designs, in smiting us, is, to turn us to himself; and if this point be not gained by lesser judgments, greater may be expected. The leaders of the people misled them. We have reason to be afraid of those that speak well of us, when we do ill. Wickedness was universal, all were infected with it. They shall be in trouble, and see no way out; and when men's ways displease the Lord, he makes even their friends to be at war with them. God would take away those they thought to have help from. Their rulers were the head. Their false prophets were the tail and the rush, the most despicable. In these civil contests, men preyed on near relations who were as their own flesh. The people turn not to Him who smites them, therefore he continues to smite: for when God judges, he will overcome; and the proudest, stoutest sinner shall either bend or break.And he shall snatch on the right hand, and be hungry,.... Either with his hand, and rob and plunder all within his reach; or, with his teeth, as cannibals, or beasts of prey, catch at, tear, and rend in pieces, whatever comes in their way; and yet hungry after more, and unsatisfied, as follows:

and he shall eat on the left hand, and they shall not be satisfied; ravage and spoil on every side, and yet not content. The Targum is,

"he shall spoil on the south, and be hungry; and he shall destroy on the north, and not be satisfied:''

they shall eat every man the flesh of his own arm; destroy their near relations, who are their own flesh and blood, or take away their substance from them; so the Targum,

"they shall spoil every man the substance of his neighbour:''

which will give some light to Revelation 17:16.
