Meaning
Of figurative uses, there are the following groups:
(1) Of the earth: Isa 66:1, Mat 5:35, Act 7:49.
(2) Of the ark: 1Ch 28:2.
(3) Of the Temple: Psa 99:5, Psa 132:7, Lam 2:1; compare Isa 60:13.
(4) Of heathen enemies subdued by the Messianic King: Psa 110:1, Mat 22:44 the King James Version; Mar 12:36, Luk 20:43, Act 2:35, Heb 1:13, Heb 10:13.
Thus the uses of this term are mainly metaphorical and symbolic of subjection, either to God as universal Lord or to God's Son as King by redemptive right. Compare 1Co 15:25-27, in which all things, including death, are represented as subject to Christ and placed beneath His feet.
