Hebrews 9:5

And over it (the ark) were cherubims of glory or glorious cherubims, (in what shape they were represented, is not certain) overshadowing the propitiatory, or seat of mercy, which was all of gold, of the same size as the ark, and like a cover to it. Just over this propitiatory were placed the two cherubs, spreading their wings looking towards one another, and upon the propitiatory. See Exodus xxxvi. and xxxvii. From this place God made known his presence, and the effects of his mercy to this people. Here he was said to be seated on the cherubims, and that the ark was his footstool. Psalm xcviii. Adore his footstool; i.e. prostrate before his ark. These two images of cherubs, shew that God did not absolutely forbid images at that time, when the people were so addicted to idolatry, but only to adore them. (Witham) --- How futile is it to object from the commandment that it is forbidden to use holy images in the Church, when we here behold even amongst the people most prone to idolatry, most gross in their ideas of spiritual things, and to whom the precept was specially given not to make any graven idols, the same God commanding these images of angels to be made and set in the most holy place of the tabernacle or temple.
