9 And the Lord will become king over all the earth; on that day the Lord will be one and his name one. 10 The whole land shall be turned into a plain from Geba to Rimmon south of Jerusalem. But Jerusalem shall remain aloft on its site from the Gate of Benjamin to the place of the former gate, to the Corner Gate, and from the Tower of Hananel to the king's wine presses. 11 And it shall be inhabited, for never again shall it be doomed to destruction; Jerusalem shall abide in security.
Matthew Henry's Commentary on Zechariah 14:9-11
Commentary on Zechariah 14:8-15
(Read Zechariah 14:8-15)
Some consider that the progress of the gospel, beginning from Jerusalem, is referred to by the living waters flowing from that city. Neither shall the gospel and means of grace, nor the graces of the Spirit wrought in the hearts of believers by those means, ever fail, by reason either of the heat of persecution, or storms of temptation, or the blasts of any other affliction. Tremendous judgments appear to be foretold, to be sent upon those who should oppose the settlement of the Jews in their own land. How far they are to be understood literally, events alone can determine. The furious rage and malice which stir up men against each other, are faint shadows of the enmity which reigns among those who have perished in their sins. Even the inferior creatures often suffer for the sin of man, and in his plagues. Thus God will show his displeasure against sin.
