Matthew Poole and continuators on Psalms 87:7

7 As well the singers as the players on instruments shall be there: all my Springs are in thee .

There shall be great rejoycing and praising God both with vocal and instrumental musick for this glorious and stupendious work of the Conversion of the Gentiles. He describes Evangelical Worship by Legal Phrases and Customs, as the Prophers frequently do.

(i. e.) In Zion or the Church. These words may be here added as the burden or matter of the Song, which these singers are supposed to have sung, and that either 1. In their own names, and in the name of all the Zionites or people of God. So the sence is, all our desires and delights are in thee, all the springs of Mercy, Grace and Glory flow to us onely in and thorow thee: for springs or fountains are oft put for all precious or desirable things, as Psal: 36. 9 Isa. 12. 3. Hos. 13. 15. Or, 2. In God's name, whose words were frequently sung by the singers in the Old Testament. 2. So the sence is, all the Springs or Fountains of good things, or of my Blessings are in Zion, or in the Church, out of which no true Blessings are to be expected or found. And this seems best to suit with the Phrase, my Springs; partly, because it seems more proper to call them God's Springs, who is the author and giver of them, than mens Springs who are onely the receivers of them; and partly, because this is more agreeable to the Phrase and Usage of Scripture which every where abscribes and appropriates them to God.
