Jeremiah 50:11

Jer 50:11 Because ye were glad, because ye rejoiced, O ye destroyers of mine heritage, because ye are grown fat as the heifer at grass, and bellow as bulls;

Ver. 11. Because ye were glad, because ye rejoiced, ] a scil., In a thing of naught, as Amo 6:13 and in the miseries of my people ye were madly merry; therefore shall ye be let bleed in the vena cava, hollow vein.

Because ye are grown fat. ] Ye have laughed yourselves fat, you have fatted yourselves as in a day of slaughter or of good cheer. It was at a feast that Babylon was taken.

And bellow as bulls. ] Or, Neigh as steeds, lusty steeds.
