Genesis 1:21

RBT Translation:

And he is cutting-out elohim אֶת-the Great Tannanim³⁷ and אֶת-the whole of the Breath of the Living-0ne, the One-who-glides-swiftly, whom they have swarmed the Dual-Waters³⁸ to-kind-them, and אֶת-the whole of a flying-one of an extremity,³⁹ to-kind-him, and he is seeing elohim for he was good.

RBT Paraphrase:

The Dragon-Serpents, Soul of Life, The Flying One Multiplies

And mighty ones is cutting out the self eternal Great Dragons and every self eternal soul of the Life, she who glides swiftly, which they have swarmed the Dual Waters to the kind of themselves, and every self eternal flyer of a wing to the kind of himself, and mighty ones is seeing, for he was good.

כלThe Whole.
The Hebrew letter "כ" (kaf) is from a pictorial letter of the "palm of the hand". The Hebrew letter "ל" stands for "staff".

Taken together this means a hand that grasps the staff of the whole. Or, the Whole is guided, shepherded by the hand that holds the staff.

The Serpent Dragon to his own Kind, i.e. Left Kind and Right Kind
"He has swallowed down the Death to victory." (Isaiah 25:8 RBT)

To his own kind.

To their own kind.

LITV Translation:
And God created the great sea animals, and all that creeps, having a living soul, which swarmed the waters, according to its kind; and every bird with wing according to its kind. And God saw that it was good.

ESV Translation:
So God created the great sea creatures and every living creature that moves, with which the waters swarm, according to their kinds, and every winged bird according to its kind. And God saw that it was good.

Brenton Septuagint Translation:
And God made great whales, and every living reptile, which the waters brought forth according to their kinds, and every creature that flies with wings according to its kind, and God saw that they were good.
