Exodus 25:18-22

The cherubim (cherubim is the plural of cherub, not cherubims) were fixed to the mercy-seat, and of a piece with it, and spread their wings over it. It is supposed these were designed to represent the holy angels, (who always attend the Shechinah, or divine majesty,) not by any effigies of an angel, but some emblem of the angelical nature, probably one or more of those four faces spoken of Ezekiel 1:10. Whatever the faces were, they looked one toward another, and both downward toward the ark, while their wings were stretched out so as to touch one another. This denotes their attendance upon the Redeemer, their readiness to do his will, their presence in the assemblies of saints, (Psalms 68:17; Psalms 1

Corinthians Exodus 11:10,) and their desire to look into the mysteries of the gospel, which they diligently contemplate, 1 Peter 1:12. God is said to dwell or sit between the cherubim, on the mercy-seat, Psalms 80:2; and from thence he here promiseth for the future to meet with Moses, and to commune with him. Thus he manifests himself willing to keep up communion with us, by the mediation of Christ.
