Why doesn't my cube rotate normally

[Joshua Waring]

I've got no idea why, I'm new to the 3D area, though I've made a nice pong in 2D.
I've compaired my code to working samples and I can't see the difference, but when I import their code it works normally, but as I said I can't see the difference.

So here it is
Before the loop is

		GL11.glMatrixMode(GL11.GL_PROJECTION);
		GL11.glLoadIdentity();
		GL11.glFrustum(-10, 10, -10, 10, 1, 10);
		GL11.glMatrixMode(GL11.GL_MODELVIEW);
		GL11.glEnable(GL11.GL_DEPTH_TEST);

and then

while(!Display.isCloseRequested()){
			GL11.glClear(GL11.GL_COLOR_BUFFER_BIT | GL11.GL_DEPTH_BUFFER_BIT);
			GL11.glClearColor(1, 1, 1, 0);
			// Draw a Cube
			GL11.glLoadIdentity();
			GL11.glRotatef(yaw, 0f, 1f, 0f);
			GL11.glRotatef(pitch, 1f, 0f, 1f);
			GL11.glBegin(GL11.GL_QUADS);
				GL11.glColor3f(1f, 0f, 0f);
				GL11.glVertex3f(-2, -2, -2);
				GL11.glVertex3f(-2, -2, -6);
				GL11.glVertex3f(-2,  2, -6);
				GL11.glVertex3f(-2,  2, -2);
					
				GL11.glColor3f(0f, 1f, 0f);
				GL11.glVertex3f(-2, -2, -2);
				GL11.glVertex3f(2, -2, -2);
				GL11.glVertex3f(2, -2, -6);		
				GL11.glVertex3f(-2, -2, -6);
					
				GL11.glColor3f(0f, 0f, 1f);
				GL11.glVertex3f(-2, -2, -6);
				GL11.glVertex3f( 2, -2, -6);
				GL11.glVertex3f( 2,  2, -6);
				GL11.glVertex3f(-2,  2, -6);
					
				GL11.glColor3f(1f, 1f, 0f);
				GL11.glVertex3f( 2,-2, -2);
				GL11.glVertex3f( 2,-2, -6);
				GL11.glVertex3f( 2, 2, -6);
				GL11.glVertex3f( 2, 2, -2);
					
				GL11.glColor3f(1f, 0f, 1f);
				GL11.glVertex3f(-2, 2, -2);
				GL11.glVertex3f( 2, 2, -2);
				GL11.glVertex3f( 2, 2, -6);
				GL11.glVertex3f(-2, 2, -6);
					
				GL11.glColor3f(1f, 1f, 1f);
				GL11.glVertex3f(-2,-2, -2);
				GL11.glVertex3f( 2,-2, -2);
				GL11.glVertex3f( 2, 2, -2);
				GL11.glVertex3f(-2, 2, -2);
			GL11.glEnd();
			
			if(Keyboard.isKeyDown(Keyboard.KEY_ESCAPE))
				break;
			Display.update();
			if(Keyboard.isKeyDown(Keyboard.KEY_LEFT))
				yaw += 1;
			if(Keyboard.isKeyDown(Keyboard.KEY_RIGHT))
				yaw += -1;
			if(Keyboard.isKeyDown(Keyboard.KEY_UP))
				pitch += 1;
			if(Keyboard.isKeyDown(Keyboard.KEY_DOWN))
				pitch += -1;
		}

I thought it would be nice to explain the problem..
Firstly, the shape seemed REALLY weird due to it being in a perspective view and the values being a bit weird. So that was changed by using glOrtho which gives a straight view.
Secondly during rotation the near clipping was being hit so a simple glTranslate on the view solved that problem (I moved it back 5)

The solution was.

GL11.glMatrixMode(GL11.GL_PROJECTION);
		GL11.glLoadIdentity();
		GL11.glOrtho(-8f, 8f, -8f, 8f, 1f, 10.0f);
		GL11.glTranslatef(0, 0, -5);
		GL11.glEnable(GL11.GL_DEPTH_TEST);
		
		
		while(!Display.isCloseRequested()){
			GL11.glClear(GL11.GL_COLOR_BUFFER_BIT | GL11.GL_DEPTH_BUFFER_BIT);
			
			GL11.glMatrixMode(GL11.GL_MODELVIEW);
			GL11.glLoadIdentity();
			
			GL11.glClearColor(1, 1, 1, 0);
			// Draw a Cube
			GL11.glLoadIdentity();
				GL11.glPopMatrix();
				GL11.glRotatef(yaw, 0f, 1f, 0f);
				GL11.glRotatef(pitch, 1f, 0f, 1f);
				GL11.glBegin(GL11.GL_QUADS);
