(1) Ho, every one that thirsteth . . .—The whole context shows that the water, the wine, the milk are all, symbols of spiritual blessings as distinctly as they are, e.g., in John 4:10; Matthew 26:29; 1 Peter 2:2. The Word “buy” is elsewhere confined to the purchase of corn, and would not rightly have been used of wine and milk. The invitation is addressed, as in a tone of pity, to the bereaved and afflicted one of Isaiah 54:6-7.
Without money and without price.—“Literally, For not-money and not-price. The prophet had used the word “buy,” but he feels that that word may be misinterpreted. “No silver or gold can buy the blessing which He offers. Something, indeed, is required, and therefore the word” buy “is still the right word; but the “price” is simply the self-surrender that accepts the blessing. Comp. Proverbs 3:14-15; Matthew 13:45-46,
I will make an everlasting covenant . . .—The words find their explanation in the “new covenant” of Jeremiah 31:31, Luke 22:20, but those which follow show that it is thought of as the expansion and completion of that which had been made with David (2 Samuel 7:12-17; Psalm 89:34-35), as the representative of the true King, whom Isaiah now contemplates as identical with the “servant of the Lord.” For “sure mercies” read the unfailing loving-kindnesses, which were “of David,” as given to him and to his seed by Jehovah.
Because of the Lord thy God . . .—The words are repeated, as expressing a thought on which the prophet loved to dwell, in Isaiah 60:9.

(The very hills, no more despoiled of trees,
Shall to the stars break forth in minstrelsies.)
The waving of the branches of the trees is, in the poet’s thoughts, what the clapping of hands is with men, a sign of jubilant exultation (Psalm 96:12).
Isaiah 55:13Instead of the thorn shall come up the fir tree, and instead of the brier shall come up the myrtle tree: and it shall be to the LORD for a name, for an everlasting sign that shall not be cut off.
