1: ὑποπόδιον
(Strong's #5286 — Noun Neuter — hupopodion — hoop-op-od'-ee-on )

from hupo, "under," and pous, "a foot," is used (a) literally in James 2:3 , (b) metaphorically, of the earth as God's "footstool," Matthew 5:35; of the foes of the Lord, Matthew 22:44 (in some mss.); Mark 12:36 , "underneath" (in some mss.); Luke 20:43; Acts 2:35; 7:49; Hebrews 1:13; 10:13 . The RV, adhering to the literal rendering, translates the phrase "the footstool of My (Thy, His) feet," for the AV, "My (etc.) footstool," but in Matthew 22:44 , "(till I put Thine enemies) underneath thy feet."
