Isaiah 28:20
For the bed is shorter than that a man can stretch himself on it: and the covering narrower than that he can wrap himself in it. For the bed is shorter than that a man can stretch himself on it: and the covering narrower than that he can wrap himself in it.
The short bed on which a person cannot stretch out and the narrow covering in which a person cannot wrap up pictures a refuge that gives neither safety nor rest. In its setting of warning against false security and of coming judgment, it shows that the protection the people trusted will fail. That chapter portrays conditions in the world today.
By the iron-bedstead rule of cutting off the one who is too long and stretching the one who is too short, it also means a pressing, crowding spirit of condemnation and oppression that judges and stops the work where the Spirit of God is manifest. That condemning spirit is offensive in God's sight, entangles churches in disunion and differences, and injures those who judge, whose own faults are graver, more than it injures the one they condemn. Instead of dwelling on matters of difference, it calls for humility and sackcloth, for mutual confession and repentance, and for seeking God's forgiveness.
