What does Leviticus 7:4 mean?

and the two kidneys, and the fat that is on them, which is by the loins, and the caul upon the liver, with the kidneys, shall he take away;

And the two kidneys, and the fat that is on them, which is by the flanks, and the caul that is above the liver, with the kidneys, it shall he take away:

and the two kidneys, and the fat that is on them, which is by the loins, and the caul upon the liver, with the kidneys, shall he take away;

And the two kidneys, and the fat on them, which is by the top of the legs, and the fat joining the liver and the kidneys, he is to take away:

and the two kidneys, and the fat which <FI>is<Fi> on them, which <FI>is<Fi> on the flanks, and the redundance above the liver (beside the kidneys he doth turn it aside);

The two little kidneys, and the fat which is by the flanks, and the caul of the liver with the little kidneys.

and the two kidneys, and the fat that is on them, which is by the flanks, and the net above the liver, which he shall take away as far as the kidneys.
