The Hebrew verb pashat has two related meanings: (1) to strip off or remove (garments, skin), and (2) to make a raid or spread out in attack. Occurring about 43 times in the OT, it describes removing priestly garments, stripping fallen warriors, and military raids. Figuratively it can describe God stripping away pride.
The stripping imagery of pashat appears at key theological moments: Aaron's priestly garments were stripped from him before his death (Numbers 20:28), symbolizing the transfer of priestly office. Jonathan stripped off his robe for David as covenant love (1 Samuel 18:4). God ultimately strips away the pretensions of idols and the proud. The gospel strips away our fig-leaf attempts at self-righteousness and clothes us in Christ's righteousness instead.
