34:24 David. See also Jeremiah 30:9; Ezekiel 37:24-25. In the coming eternal age of Christ’s kingdom on the renewed earth, the Lord Jesus will occupy “the throne of his father David” (Luke 1:32), which will continue “for ever” (Luke 1:33). In the millennial kingdom preceding this, it seems that David himself, resurrected from the dead with the other Old Testament saints when Christ was resurrected (Matthew 27:52,53), will sit upon the physical throne in Jerusalem.
34:26 showers. During the long centuries of Israel’s worldwide dispersion, the promised land had become largely a desert, and the former rainfall regimes had failed. With the modern return of the exiles, however, the lands have been substantially reclaimed, and the rains have returned in measure.
34:26 showers of blessing. This felicitous phrase provided the inspiration for the well-known gospel hymn with that name. The word translated “showers” is frequently translated “rain,” and is first used in Genesis 7:12, speaking of the “rain” that came down for forty days and nights to destroy the incurably wicked antediluvian population, thus serving as a blessing to those that were saved on the ark from being engulfed in that wickedness.
34:29 plant of renown. Literally, “a plant of the Name,” prophesying the coming reign of Messiah, whose rule would assure full security and provision of all needs. When He came first, He was “as a tender plant, and as a root out of a dry ground” (Isaiah 53:2), with “no beauty that we should desire Him,” but then He shall be a Plant of Renown.
