EXPOSITION
THIS short psalm, opening with the praise of Zion, or of the Jewish Church (Psalms 87:1-3), passes into a glorification of the Church universal, when all the nations have come into it (Psalms 87:4-7). The glorification falls under two heads—God's acknowledgment of those who flock into his Church (Psalms 87:4-6), and their acknowledgment of the blessings which they receive through it. The two "selahs" divide the psalm into two stanzas, each of three verses, and a short epode consisting of a single verse.
