Gen. 1:28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.

Subdue from the 1828 Webster Dictionary:
1. To conquer by force or the exertion of superior power, and bring into permanent subjection; to reduce under dominion. Subduing implies conquest or vanquishing, but it implies also more permanence of subjection to the conquering power, than either of these words.
I will subdue all thine enemies. 1 Chronicles 17:10.
2. to crush; to sink; to overpower so as to disable from further resistance.
3. To tame; to break by conquering a refractory temper or evil passions; to render submissive; as, to subdue a stubborn child.
4. To conquer; to reduce to mildness; as, to subdue the temper or passions.
5. To overcome by persuasion or other mild means; as, to subdue opposition by argument or intreaties.
6. To overcome; to conquer; to captivate; as by charms.
7. To soften; to melt; to reduce to tenderness; as, to subdue ferocity by tears.

Subdue is good when the conquering power is God!!
