Charles H. Spurgeon on Psalms 132:7

(first clause.) Tabernacles are spoken of in the plural number, and this it may be (though we may doubt whether the Psalmist had such minute distinctions in his eye) because there was in the Temple an inner sanctuary, a middle apartment, and then the court. It is of more importance to attend to the epithet which follows, where the Psalmist calls the Ark of the Covenant God's footstool, to intimate that the sanctuary could never contain the immensity of God's essence, as men were apt absurdly to imagine. The mere outward Temple with all its majesty being no more than his footstool, his people were called upon to look upwards to the heavens, and fix their contemplations with due reverence upon God himself. —John Calvin.
