John Gill Commentary Zechariah 14:3

"Then shall Jehovah go forth, and fight against those nations, as when he fought in the day of battle." — Zechariah 14:3 (ASV)

Then shall the Lord go forth Out of his place in heaven, either in person, or by the display of his power; that is, the Lord Jesus Christ; whose name is called the Word of God, and is the King of kings, and Lord of lords, described as a mighty warrior, (Revelation 19:11) : and fight against those nations, as when he fought in the day of battle :

the Targum adds, "at the Red Sea"; when the Lord fought for, Israel against the Egyptians, (Exodus 14:25) and afterwards against the Canaanites, when they entered the land of Canaan under Joshua:

thus Christ shall judge, and make war in righteousness, and overcome those that shall make war with him; and with the sharp sword that goeth out of his mouth shall smite nations, and with a rod of iron rule them, and break them to shivers, (Revelation 14:14) (Revelation 19:11Revelation 19:15) (2:27) see also (Ezekiel 38:21Ezekiel 38:22) (Ezekiel 39:1Ezekiel 39:8Ezekiel 39:4) .
