Charles Ellicott Commentary Jeremiah 5:27

"As a cage is full of birds, so are their houses full of deceit: therefore they are become great, and waxed rich." — Jeremiah 5:27 (ASV)

A cage. —The large wicker basket (Amos 8:1–2) in which the fowler kept the birds he had caught, or, possibly, used for decoy-birds.
