'Itself' in the Bible

Should an axe brag against him who chops with it? Should a saw exalt itself above him who saws with it? As if a rod should lift those who lift it up, or as if a staff should lift up someone who is not wood.

This shall be the sign to you. You will eat this year that which grows of itself, and in the second year that which springs from the same; and in the third year sow and reap and plant vineyards, and eat their fruit.

Why do you spend money for that which is not bread? and your labor for that which doesn't satisfy? listen diligently to me, and eat you that which is good, and let your soul delight itself in fatness.

Your sun shall no more go down, neither shall your moon withdraw itself; for Yahweh will be your everlasting light, and the days of your mourning shall be ended.
