a feast(lit. "banquet") of fat things … full of marrow The fat parts of the animal, which in ordinary sacrifice were reserved for the deity, were regarded in the East as the choicest delicacy.

wines on the lees well refined i.e. wine that has been left to stand long on its sediment, in order that its strength, flavour, bouquet, &c., might be enhanced by repeated fermentation (cf. Jeremiah 48:11; Zephaniah 1:12). Such old wines had to be strained before being used; hence the expression "well-refined" in E.V. The choice of terms in the Hebr. is partly dictated by the assonances: fat thingscorresponding to wines on the lees, and full of marrowto well refined. For the image of the feast as an emblem of the blessings of the kingdom of God cf. ch. Isaiah 55:1-2; Psalms 23:5; Matthew 8:11; Matthew 22:2 ff.; Luke 14:15 ff.; Revelation 19:9.
