Jeremiah 4:14
O Jerusalem, wash thine heart from wickedness, that thou mayest be saved. How long shall thy vain thoughts lodge within thee? O Jerusalem, wash thine heart from wickedness, that thou mayest be saved. How long shall thy vain thoughts lodge within thee?
Jerusalem is summoned to wash its heart clean of wickedness so that it may be saved. Deliverance is made to depend on turning away from inward sin, not on outward appearances alone. Repentance and moral reform are therefore presented as urgently necessary, to be undertaken without delay.
