'Beasts' in the Bible

and every first-born in the land of Egypt hath died, from the first-born of Pharaoh who is sitting on his throne, unto the first-born of the maid-servant who is behind the millstones, and all the first-born of beasts;

And it cometh to pass, at midnight, that Jehovah hath smitten every first-born in the land of Egypt, from the first-born of Pharaoh who is sitting on his throne, unto the first-born of the captive who is in the prison-house, and every first-born of beasts.

that thou hast caused every one opening a womb to pass over to Jehovah, and every firstling -- the increase of beasts which thou hast: the males are Jehovah's.
