Piece of furniture for resting the feet, especially for one seated on a throne (2 Chron 9:18; James 2:3). The footstool of Tutankhamen of Egypt was carved with pictures of his enemies. Other Pharaohs were portrayed with their feet on their enemies’ heads. The footstool thus became a symbol for dominion. God is pictured as a king enthroned in heaven with the earth as His footstool (Isa 66:1; Matt 5:35). In Ps 99:5 and Lam 2:1 it is difficult to determine with certainty whether God’s footstool is the ark, the temple, or Zion (Isa 60:13, Ezek 43:7). Only 1 Chron 28:2 is an unambiguous reference to the ark as a resting place for God’s feet.
In Ps 110:1 God makes the messianic King triumph over His enemies, who are then made His footstool. This text is quoted six times in the NT. It served as the basis for Jesus’ riddle about David’s son who is also his Lord (Matt 22:44; Mark 12:36; Luke 20:43). Elsewhere, the scripture was applied to the ascension of Christ (Acts 2:34-35), the exaltation of Christ (Heb 1:13), and the future victory of Christ (Heb 10:13).
