footstool

connected with a throne (2 Chr. 9:18)

Jehovah symbolically dwelt in the holy place between the cherubim above the ark of the covenant. The ark was his footstool (1 Chr. 28:2; Ps. 99:5; 132:7).

And as heaven is God's throne, so the Earth is his footstool (Ps. 110:1; Isa. 66:1; Matt. 5:35).
