What is the first message sent by telegraph? What does it mean?

On May 24, 1844, Samuel F. B. Morse sent his first telegram message, "What hath God wrought?" from Washinton to the B&O Railways warehouse in Baltimore. The sentence is taken from the Bible (23:23) and is not actually written to make a deep sense. Annie Ellsworth, the little daughter of Morse's close friend, chose what to write in the message. It refers to that verse of Bible:

23 There is no divination against Jacob,
no evil omens against Israel.
It will now be said of Jacob
and of Israel, 'See what God has done!'
