'Exactly' in the Bible

Moses and Aaron were brought back to Pharaoh and he told them, "Go, serve the LORD your God. But exactly who will go?"

All the Israelis did this. They did exactly as the LORD commanded Moses and Aaron.

When they measured it with a vessel the capacity of which was one omer, the one who gathered much did not have an excess, while the one who gathered little did not lack. They gathered exactly what each needed to eat.
