The Hebrew noun mebusah refers to the action of treading down or trampling — used both literally of armies trampling a land and figuratively of oppression that crushes the dignity of persons.
Mebusah appears in prophetic oracles of judgment where enemy nations or internal oppressors trample the covenant people. Isaiah 22:5 describes a day of trampling and confusion in the valley of vision. Yet this same imagery is reversed in eschatological hope — the enemies who trampled God's people will themselves be trodden underfoot (Isaiah 14:19). The trampling imagery also points forward to the language of Revelation, where evil is finally and decisively crushed under the feet of the Lord of hosts.
