Albert Barnes Commentary Ezekiel 27:6

"Of the oaks of Bashan have they made thine oars; they have made thy benches of ivory inlaid in boxwood, from the isles of Kittim." — Ezekiel 27:6 (ASV)

The company ... ivory - Rather, “your benches (or, deck) they made of ivory with boxwood” (or, larch), that is, boxwood inlaid with ivory.

The isles - (or, coasts) of Chittim is a phrase used constantly for Greece and the Grecian islands. It may probably be extended to other islands in the Mediterranean Sea (Genesis 10:5), and there ivory may have been brought from the coasts of North Africa.
