Isaiah 25:6 - Ellicott's Commentary On The Whole Bible

And in this mountain shall the Lord... — The mountain is, as in Isaiah 2:1, the hill of Zion, the true representative type of the city of God. True to what we may call the catholicity of his character, Isaiah looks forward to a time when the outlying heathen nations shall no longer be excluded from fellowship with Israel, but shall share in its sacrificial feasts even as at the banquet of the great King. In the Hebrew, as even in the English, the rhythm flows on like a strain of music appropriate to such a feast. The “wines on the lees” are those that have been allowed to ripen and clarify in the cask, and so, like the “fat things full of marrow,” represent the crowning luxuries of an Eastern banquet.
