Charles H. Spurgeon on Psalms 84:3

Even thine altars. There were two altars; the "brazen altar, "and the "golden altar; "to those, no doubt, the psalmist refers. Both were of shittim wood, which sets forth the holy humanity —the perfect manhood, of the Lord Jesus. Incarnation lies at the foundation of all his work for us, and all our blessing in him. The one altar was overlaid with brass, the other with pure gold. The overlaying shadows forth his Godhead, but in distinct aspects. We have the same Jesus in both, but shadowed forth in different circumstances. In the one, humiliation and suffering; in the other, exaltation and glory. Things New and Old.
