Adam Clarke Bible Commentary

Because of the dearth - About the time of Zerubbabel, God had sent a judicial dearth upon the land, as we learn from Haggai, Hag 1:9, etc., for the people it seems were more intent on building houses for themselves than on rebuilding the house of the Lord: "Ye looked for much, and, lo, it is come to little; because of mine house that is waste; and ye run, every man unto his own house. Therefore the heaven over you is stayed from dew, and the earth is stayed from her fruit. And I called for a drought upon the land, and upon the mountains, and upon the corn, and upon the new wine, and upon the oil, and upon that which the ground brought forth; and upon men, and upon cattle, and upon all the labor of the hands." This dearth might have been continued, or its effects still felt; but it is more likely that there was a new dearth owing to the great number of people, for whose support the land that had been brought into cultivation was not sufficient.
