John Gill Commentary Zechariah 10:5

"And they shall be as mighty men, treading down [their enemies] in the mire of the streets in the battle; and they shall fight, because Jehovah is with them; and the riders on horses shall be confounded." — Zechariah 10:5 (ASV)

And they shall be as mighty [men]
That is, the converted Jews shall be such; they shall be strong in faith, giving glory to the Messiah; they shall be strong in the grace that is in him; they shall be strong in the Lord, and in the power of his might; his strength shall be made perfect in their weakness:

which tread down [their enemies] in the mire of the streets in the
battle ;
being victorious over sin, Satan, and the world, through Christ, in whom they will believe: and they shall fight ;
against all their inward and outward enemies, the good fight of faith, with great valour and courage:

because the Lord [is] with them ;
who is the Lord of hosts or armies; his presence gives boldness and intrepidity; for, if he is for them, who can be against them? the battle is theirs, success is certain:

and the riders on horses shall be confounded ;
such that come up against them on them, and trust in them, shall be beaten by them, and so made ashamed; and the flesh, both of the horses and their riders, shall be the food of the fowls of the air, (Revelation 19:18) perhaps the Turkish cavalry is meant, who may attempt to hinder the settlement of the Jews in their own land; the armies of the Turks consisting greatly of horsemen, (Revelation 9:16) .
