Genesis 1:11

Let the earth bring forth. After the separation of dry land from the water, another divine order was given on that third day: vegetation was summoned into existence. Some have considered the first of the three terms employed in the divine command a general term for plants, including the second and the third. However, it is preferable to take them as distinct classes.

Grass. Heb., deshe‘, “to be green,” “to grow green.” “to sprout.” This word designates green sprouts and tender herbs — the various kinds of plants that supply food for the animals. “Grass” is probably used here as a synonym of the word “herb,” ‘eseb, when the latter appears without the qualifying expression “yielding seed” (see v. 30; Ps. 23:2).

The herb yielding seed. “Herb,” ‘eseb, is the more mature herbage, in which the seed is the most striking characteristic, providing one of the two kinds of food designated by God to be consumed by human beings, (v. 29).

The fruit tree. Three characteristics of fruit-bearing trees are here noted: (1) the bearing of fruit, (2) the enclosing of seed within the fruit, and (3) the bearing of this fruit “upon” or above the earth. These trees were to provide man with another source of food (v. 29).
