Targum Pseudo-Jonathan on Genesis 9:17 closes the rainbow passage with a final seal. Noah is told face to face: This is the sign of the covenant that I have covenanted between My Word and between the word for all flesh that is upon the earth.
The Aramaic repeats the formula three times across just a few verses. Word. Word. Word. The Memra, the living divine Word, is the partner in this covenant, and every breathing thing is the other party. The triple repetition is a Jewish legal move, the way an oath is sealed by stating it in the mouth of a witness more than once.
Stop and hear what the Targum is doing. By naming the Memra as one of the signatories, the Aramaic is guarding the covenant from ever being reinterpreted as a fragile handshake. This is not a promise that can weaken with time. It is held open by the same Word that spoke light into being.
And Noah, standing on a muddy new earth under a fresh sky, hears the words as the very last formal conversation he will have with the Holy One in Torah. After this, the narrative turns toward human life, the vineyard, the descendants.
The takeaway: the last thing God says to Noah is a promise of constancy. Go forward, Noah. The sky has been settled.
