Shālaph (שָׁלַף) means to draw out, to pull out, to unsheathe — particularly drawing a sword from its scabbard. Also used for pulling off a sandal (Ruth 4:7-8).
Judges 3:22: Ehud plunged his sword into Eglon's belly, and 'even the handle sank in... and Ehud did not draw the sword out.' Judges 8:20: Gideon told Jether to 'draw your sword and kill them' — but the boy was afraid. Ruth 4:7-8: the kinsman-redeemer 'drew off his sandal' — transferring rights. Drawing the sword represents decisive action. Hebrews 4:12: 'The word of God is alive and active, sharper than any double-edged sword.' When God's Word is drawn, it accomplishes its purpose.
