parah, “to bear fruit,” strong’s H6509

First occurrence

And God blessed them, saying: “Be fruitful, and multiply, and fill the waters in the seas, and let birds multiply in the earth.” Gen 1:22

Hebrew root

Strong’s H6509 פרה parah, a primitive root meaning “to bear fruit.” The pictographs are pey + resh + hey:

pey פ , ף = the mouth, thus open, blow, scatter, edge
resh ר = the head of man, thus head, first, top, beginning, man
hey ה = the man with upraised arms, thus look, reveal, wonder, worship, breath

To understand the story, we have to know something about threshing grain in ancient days:

“The heads of grains are scattered on the threshing floor, a smooth, hard and level surface. An ox is led around the floor crushing the heads, opening them to reveal the seed inside.” – Ancient Hebrew Lexicon

The story the pictographs are telling is of opening (pey) the head (resh) of grain which reveals (hey) the seed inside; i.e. acquiring seed. One of the nouns derived from this root is fruit, as that which the seed thus acquired produces.
