Ibn Ezra
His servant. The prophet himself.44I. E. here neglects the rule of the parallelism, which he repeatedly recommends; for that rule demands that עברו and מלאכיו should have the same meaning) and since the latter is a plural, signifying his messengers, עבדו is likewise to be taken in a collective sense, and referred not only to the one prophet who is here speaking, but to all prophets. The word of his servant, that Jerusalem shall be inhabited.
Rashi
and the counsel of His messengers One angel said to Jacob (Gen. 32:27), “Israel shall be your name,” and I fulfilled his words. Here too, I will fulfill the counsel of My prophets who say concerning Jerusalem, “It shall be settled.”
