What does Numbers 24:16 mean?

'I see him, but not right now. I look at him, but he’s not close. A star will come out of Jacob, a ruler will rise from Israel. He’ll crush the heads of Moab and destroy all the sons of Sheth.' Numbers 24:16 - Modern Text Bible

(Balaam predicts a future leader from Israel who will defeat Moab and other enemies—a prophecy often seen as messianic.)
