Psalm 87 is the fulfillment of the Feast of Tabernacles, just as Psa. 84 was of the Feast of Trumpets, and as Psa. 85 is the fulfillment of the Day of Atonement.
Of the sons of Korah. A Psalm. A Song.
1 His foundation is in the mountains of holiness.
2 Jehovah loveth the gates of Zion more than all the habitations of Jacob.
3 Glorious things are spoken of thee, O city of God. Selah.
4 I will make mention of Rahab and Babylon among them that know me; behold Philistia, and Tyre, with Ethiopia: this man was born there.
5 And of Zion it shall be said, This one and that one was born in her; and the Most High himself shall establish her.
6 Jehovah will count, when he inscribeth the peoples, This man was born there. Selah.
7 As well the singers as the dancers shall say, All my springs are in thee.
