So the heathen shall fear the name of the LORD, and all the kings of the earth thy glory.
So - as the blessed result of the Lord's having mercy upon Zion.
The heathen shall fear the name of the Lord - the strongest plea to urge an appeal to the Lord's own glory, as involved in the restoration of Zion (Psalms 68:29-32; Isaiah 59:19-20). All the tenses in Psalms 102:16-17 are preterites-faith and prophecy regarding the event as sure no if it were actually come to pass.
