Ezekiel 16:27
27
Behold, therefore I have stretched out my hand over thee, and have diminished thy ordinary food, and delivered thee to the will of them that hate thee, the daughters of the Philistines, who are ashamed of thy lewd way.
Reach
The hand in the Bible represents power, which is easy to understand, so to reach out or stretch out the hand means to exercise power, to put it to work. This is an image that's used a great deal in the stories of Moses, who repeatedly stretched out his hand (or his rod, which represents a more external kind of power) to bring plagues on Egypt and perform other miracles. This is a correspondence that makes sense, since we reach out constantly to use our hands to do our work.
