דָּג Strong’s #1709 dag

And the fear of you and the dread of you shall be upon every beast of the earth, and upon every bird of the heavens; With all wherewith the ground teemeth, and all the fishes of the sea, into your hand are they delivered.

Genesis 9:2

In the original pictographic script used to write Hebrew, and other Semitic languages, this word was written with the picture of a door, the letter dalet, representing a “back and forth movement” and the picture of a “foot,” the letter gimel. When these two letters are combined we have “the back and forth movement of the foot/tail,” a perfect image for a “fish.” Interestingly, the “a” in the Hebrew word dag is pronounced with a short “a” and would therefore be pronounced like our word “dog,” another animal with a “tail that moves back and forth.” Because of the abundance of fish caught in nets, this word is the origin of another Hebrew word: dagah (Strongs #1711) meaning “abundance.”
