At that time they shall call Jerusalem the throne of the LORD; and all the nations shall be gathered unto it, to the name of the LORD, to Jerusalem: neither shall they walk any more after the imagination of their evil heart.
Jerusalem - the whole city, not merely the temple. As it has been the center of the Hebrew theocracy, so it shall be the point of attraction to the whole earth (Isaiah 2:2-4; Zechariah 2:10-11; Zechariah 14:16-21).
The throne of the Lord - the Shekinah, the symbol of God's special nearness to Israel (Deuteronomy 4:7), shall be surpassed by the antitype, God's own throne in Jerusalem (Psalms 2:6; Psalms 2:8; Ezekiel 34:23-24; Zechariah 2:5).
Imagination - rather, as margin, 'the obstinacy' or stubbornness х shªriruwt (H8307), from shaarar (H8324), to be hard].
