The LORD's voice crieth unto the city, and the man of wisdom shall see thy name: hear ye the rod, and who hath appointed it.
The Lord's voice crieth unto the city - Jerusalem.
And the man of wisdom. As in Proverbs 13:6, Hebrew, 'sin' is used for 'a man of sin;' and in Psalms 109:4, "prayer" for 'a man of prayer;' so here "wisdom" for 'the man of wisdom.'
Shall see thy name - shall regard thee, in thy revelations of thyself. Compare the end of Micah 2:7, "Do not my words do good to hits that walketh uprightly?" God's "name" expresses the sum total of His revealed attributes (Micah 5:4, "He shall stand and feed in the majesty of the name of the Lord His God"). Contrast with this Isaiah 26:10, "The wicked will not behold the majesty of the Lord." Another reading is adopted by the Septuagint, Syriac, and Vulgate, 'there is deliverance for those who fear х yir'eey (H3372) for yir'eh (H3070)] thy name.' The English version is better suited to the connection; and the rarity of the Hebrew expression, as compared with the frequency of that in the other reading, makes the English version reading less likely to be an interpolation.
Hear ye the rod, and who hath appointed it - hear what punishment (cf. Micah 6:13, etc.; Isaiah 9:13; Isaiah 10:5; Isaiah 10:24, "O Assyrian, the rod of mine anger, and the staff in their hand is mine indignation") awaits you, and from whom. I am but a man, and so ye may disregard me; but remember my message is not mine, but God's. Hear the rod when it is come, and you feel its smart. Hear what counsels, what cautions it speaks.
Appointed it - (Jeremiah 47:7, "How can it (the sword of the Lord) be quiet, seeing the Lord hath given it a charge against Ashkelon, and against the sea shore? there hath he appointed it").
