The mode of taking an oath, alluded to in Genesis 24:2-9 47:29-31 , was significant of the swearer's obligation to obedience. Jacob's thigh was disabled by the Angel, to show the patriarch that his prevalence was through his faith and prayer, not through force, Genesis 32:25-31 . Smiting the thigh was a gesture of self-condemnation and grief, Jeremiah 31:19 Ezekiel 21:12 . Warriors wore their swords upon the left thigh, unless left-handed in readiness for use, Judges 3:15-21 Psalm 45:3 Song of Song of Solomon 3:8; so too they may have borne their names and titles, not only on their shields, but on their swords, or on the rove or mailed coat covering the thigh, Revelation 19:16 . "Hip and thigh," Judges 15:8 , seems to mean utterly and irrecoverably.
