The Torah ends the sixth day's first act with a simple line: God saw that it was good. Targum Pseudo-Jonathan on (Genesis 1:25) repeats the clean/unclean doubling — beast of the earth, cattle, creeping thing, each after its kind, in both categories — and then God's verdict lands: tav. Good.
Notice what God does not say. He does not say the unclean creatures are bad. They too are called good. In Jewish thought, the later categories of permitted and forbidden food are about human holiness and discipline, not about creatures being flawed. A pig is a good pig. It is simply not for us to eat. The Targumist's careful repetition preserves this: every kind the earth produced was blessed, even those Israel would later be told to leave alone.
