John Gill Commentary Jeremiah 27:19

"For thus saith Jehovah of hosts concerning the pillars, and concerning the sea, and concerning the bases, and concerning the residue of the vessels that are left in this city," — Jeremiah 27:19 (ASV)

For thus saith the Lord of hosts concerning the pillars
The pillars of brass that stood in the temple; the one called Boaz, and the other Jachin, (1 Kings 7:15 1 Kings 7:21) ; and concerning the sea ;
the sea of molten brass, which stood upon twelve oxen, (1 Kings 7:23 1 Kings 7:25) ; and concerning the bases :
the ten bases, which also were made of brass, (1 Kings 7:27–37) ; and concerning the residue of the vessels that remain in this city ;
in the king's palace, and in the houses of the noblemen, and of the rich and wealthy inhabitants of Jerusalem.
