The first occurrence.
And God saw every thing that He had made, and, behold, it was very good. And the evening and the morning were the sixth day. Gen 1:31
The primitive root.
Strong’s H3966 me’od, an adjective meaning, “very, abundantly;” from an unnamed, unused primitive root meaning, “to rake together.” The 3-letter root of the adjective is mem + aleph + dalet.
mem מ ם = the water, thus chaos, mighty, blood
aleph א = the ox head, thus strength, power, leader
dalet ד = the door, thus enter, move, hang
Some of the cognate words from the unnamed root are smoke, charcoal, and firebrand, as the charred remains of a fire are raked together to collect the ash, so a powerful (aleph) movement back and forth (dalet, as the door moves back and forth on its hinges) indicates a raking together. The story: A mighty (mem) raking together (aleph + dalet) of things, actions, or character.
