א בַּיּוֹם הַהוּא יוּשַׁר הַשִּׁיר הַזֶּה בְּאֶרֶץ יְהוּדָה עִיר עָז לָנוּ יְשׁוּעָה יָשִׁית חוֹמוֹת וָחֵל

The prophet returns to the song of the future redemption. On that day of the redemption, this song will be sung in the land of Judah: Ours is a mighty city; He will place salvation in walls and rampart. Alternatively, the salvation that God will bring to the city will provide protection like the walls and rampart.

ב פִּתְחוּ שְׁעָרִים וְיָבֹא גוֹי צַדִּיק שֹׁמֵר אֱמֻנִים

The prophet addresses the redeemed city of Jerusalem: Prayer and praise to God will be recited in your midst. Therefore, open your gates, and a righteous nation, the keeper of unwavering faith in God, will enter.
