Psalmen 87:5

Inasmuch now as the nations come thus into the church (or congregation) of the children of God and of the children of Abraham, Zion becomes by degrees a church immeasurably great. To Zion, however, or of Zion (ל of reference to), shall it be said אישׁ ואישׁ ילּד־בּהּ. Zion, the one city, stands in contrast to all the countries, the one city of God in contrast to the kingdoms of the world, and אישׁ ואישׁ in contrast to זה. This contrast, upon the correct apprehension of which depends the understanding of the whole Psalm, is missed when it is said, "whilst in relation to other countries it is always only the whole nation that comes under consideration, Zion is not reckoned up as a nation, but by persons" (Hofmann). With this rendering the ילּד retires into the background; in that case this giving of prominence to the value of the individual exceeds the ancient range of conception, and it is also an inadmissible appraisement that in Zion each individual is as important as a nation as a whole. Elsewhere אישׁ אישׁ, Lev 17:10, Lev 17:13, or אישׁ ואישׁ, Est 1:8, signifies each and every one; accordingly here אישׁ ואישׁ (individual and, or after, individual) affirms a progressus in infinitum, where one is ever added to another. Of an immeasurable multitude, and of each individual in this multitude in particular, it is said that he was born in Zion. Now, too, והוּא כוננה עליון has a significant connection with what precedes. Whilst from among foreign peoples more and more are continually acquiring the right of natives in Zion, and thus are entering into a new national alliance, so that a breach of their original national friendships is taking place, He Himself (cf. Sa1 20:9), the Most High, will uphold Zion (Psa 48:9), so that under His protection and blessing it shall become ev…

The foregoing psalm was very plain and easy, but in this are things dark and hard to be understood. It is an encomium of Zion, as a type and figure of the gospel-church, to which what is here spoken is very applicable. Zion, for the temple's sake, is here preferred, I. Before the rest of the land of Canaan, as being crowned with special tokens of God's favour (Psa 87:1-3). II. Before any other place or country whatsoever, as being replenished with more eminent men and with a greater plenty of divine blessings (Psa 87:4-7). Some think it was penned to express the joy of God's people when Zion was in a flourishing state; others think it was penned to encourage their faith and hope when Zion was in ruins and was to be rebuilt after the captivity. Though no man cared for her (Jer 30:17, "This is Zion whom no man seeketh after"), yet God had done great things for her, and spoken glorious things of her, which should all have their perfection and accomplishment in the gospel-church; to that therefore we must have an eye in singing this psalm. A psalm or song for the sons of Korah.
