King James Bible
"And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven."
God commands the waters to teem with living creatures, marking the fifth day of creation. The phrase emphasizes both God's sovereign speech as the means of creation and the waters as the designated realm for aquatic life, establishing the sea as a distinct habitat filled with diverse organisms. Birds are created to inhabit the sky, described as the 'open firmament' or expanse established on day two. This parallel creation of sea and sky creatures on the same day links these two fluid environments, both requiring creatures designed for movement through their respective mediums.
