Charles Ellicott Commentary Ezekiel 24:4

"gather the pieces thereof into it, even every good piece, the thigh, and the shoulder; fill it with the choice bones." — Ezekiel 24:4 (ASV)

The pieces of it. —Literally, its pieces, the pieces which pertain to the cauldron, the Jews, whose centre and capital is Jerusalem. This was the natural effect of Nebuchadnezzar’s campaign; the people from every side sought refuge in the city . The mention of the good piece, the choice bones, and the choice of the flock (Ezekiel 24:5), is not for the purpose of designating any particular class, but only to emphasise that all, even the best, are to be included.
