And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.

Wesley's Notes

1:24-25 We have here the first part of the sixth day's work. The sea was the day before replenished with fish, and the air with fowl; and this day are made the beasts of the earth, cattle, and the creeping things that pertain to the earth. Here, as before,
(1.) The Lord gave the word: he said, Let The earth bring forth - Let these creatures come into being upon the earth, and out of it, in their respective kinds.
2. He also did the work; he made them all after their kind - Not only of divers shapes, but of divers natures, manners, food, and fashions: In all which appears the manifold wisdom of the Creator.

Scofield Reference Notes

The sixth day: (1) the fecundity of the earth after the creative work of the fifth day.

[2] living creature

"Creature," Heb. nephesh, trans. soul in Gen 2.7 and usually. In itself nephesh, or soul, implies self-conscious life, as distinguished from plants, which have unconscious life. In the sense of self-conscious life animals also have "soul." See verses Gen 1:26,27 2:7,21-23. See Scofield Note: "Gen 1:26".

Jamieson-Fausset-Brown Bible Commentary

Ge 1:24-31. Sixth Day. A farther advance was made by the creation of terrestrial animals, all the various species of which are included in three classes: (1) cattle, the herbivorous kind capable of labor or domestication.

24. beasts of the earth-(2) wild animals, whose ravenous natures were then kept in check, and (3) all the various forms of creeping things-from the huge reptiles to the insignificant caterpillars.

Matthew Henry's Concise Commentary

1:20-25 God commanded the fish and fowl to be produced. This command he himself executed. Insects, which are more numerous than the birds and beasts, and as curious, seem to have been part of this day's work. The Creator's wisdom and power are to be admired as much in an ant as in an elephant. The power of God's providence preserves all things, and fruitfulness is the effect of his blessing.
