'Rod' in the Bible

I am to him for a father, and he is to Me for a son; whom in his dealings perversely I have even reproved with a rod of men, and with strokes of the sons of Adam,

And he hath smitten the Egyptian man, a man of appearance, and in the hand of the Egyptian is a spear, and he goeth down unto him with a rod, and taketh violently away the spear out of the hand of the Egyptian, and slayeth him with his own spear.
