The poetic reversal continues. While verse 16 described the power reversal, verse 17 shows the reversal of possessing food. The land that the wealthy had accumulated will become common pastures. According to Ludlow:
“The “waste places of the fat ones” probably refers to the now desolate lands of the once rich and prosperous. Some translations describe “kids” or goats eating the land, while others record that “strangers” will feed in the area. The term used depends upon which early Old Testament version is followed—the Hebrew Masoretic text uses the word for “aliens” in this verse, while the Greek Septuagint has the word for “young goats.”
As poetry, kids/lambs is a better parallel. Further, the concept of wealth being returned to the common people also favors “kid” over “stranger.”
