What does Malachi 1:4 mean?

Whereas Edom saith, We are beaten down, but we will return and build the waste places; thus saith Jehovah of hosts, They shall build, but I will throw down; and men shall call them The border of wickedness, and The people against whom Jehovah hath indignation for ever.

Whereas Edom saith, We are impoverished, but we will return and build the desolate places; thus saith the Lord of hosts, They shall build, but I will throw down; and they shall call them, The border of wickedness, and, The people against whom the Lord hath indignation for ever.

Whereas Edom saith, We are beaten down, but we will return and build the waste places; thus saith Jehovah of hosts, They shall build, but I will throw down; and men shall call them The border of wickedness, and The people against whom Jehovah hath indignation for ever.

Though Edom says, We are crushed down but we will come back, building up the waste places; this is what the Lord of armies has said: They may put up buildings, but I will have them pulled down; and they will be named The land of evil-doing, and The people against whom the Lord keeps his wrath for ever.

Because Edom saith, `We have been made poor, And we turn back and we build the wastes,' Thus said Jehovah of Hosts: They do build, and I do destroy, And <FI>men<Fi> have called to them, `O region of wickedness,' `O people whom Jehovah defied to the age.'

But if Edom shall say: We are destroyed, but we will return and build up what hath been destroyed: thus saith the Lord of hosts: They shall build up, and I will throw down: and they shall be called the borders of wickedness, and the people with whom the Lord is angry for ever.

If Edom say, We are broken down, but we will build again the ruined places, — thus saith Jehovah of hosts: They shall build, but I will throw down; and [men] shall call them the territory of wickedness, and the people against whom Jehovah hath indignation for ever.
