In Balaam's oracle, what "will come forth from Jacob"?

Answer: A star

Balaam said, "A star will come forth from Jacob, and a scepter will arise from Israel" (Numbers 24:17).

“I see him, but not now; I behold him, but not near. A star will come forth from Jacob, and a scepter will arise from Israel. He will crush the skulls of Moab and strike down all the sons of Sheth.”— Numbers 24:17 (BSB)
