Adam Clarke's Bible Commentary Verse 1. His foundation is in the holy mountains. ] Jerusalem was founded on the mountains or hills of Zion and Moriah. The after increase of the population obliged the inhabitants to inclose all the contiguous hills; but Zion and Moriah were the principal. We know that ancient Rome was built on seven hills.
Matthew Henry Commentary
Verses 1-3 - Christ himself is the Foundation of the church, which God has laid Holiness is the strength and firmness of the church. Let us not be ashamed of the church of Christ in its meanest condition, nor of thos that belong to it, since such glorious things are spoken of it. Othe foundation can no man lay than that is laid, even Jesus Christ. The glorious things spoken of Zion by the Spirit, were all typical of Christ, and his work and offices; of the gospel church, its privilege and members; of heaven, its glory and perfect happiness.
