John Trapp on Psalms 78:31

Verſ. 31. The wrath of God came upon them] Heb. Aſcended, as a flame, which the bigger it groweth, the higher it getteth.

And ſlew the fatteſt of them] Thoſe that had glutted and ſtuffed themſelves like a wool-pack, being nitida & bene curata cute pingues, fat and fair-liking.

And ſmote down the choſen men of Iſrael] Or, The young men, who by a haſty Teſtament bequeathed that new name Kibroth hattaanah, that is, the graves of luſt, to the place they lay buried in.
