'Fitting' in the Bible

God called the dry land earth, and the gathering of the waters He called seas; and God saw that this was good (pleasing, useful) and He affirmed and sustained it.

to rule over the day and the night, and to separate the light from the darkness; and God saw that it was good and He affirmed and sustained it.

So God made the wild animals of the earth according to their kind, and the cattle according to their kind, and everything that creeps and crawls on the earth according to its kind; and God saw that it was good (pleasing, useful) and He affirmed and sustained it.
