What did Manolin give Santiago two of before he left?

Manolin gave Santiago two baits.

“May I get the sardines? I know where I can get four baits too.”
“I have mine left from today. I put them in salt in the box.”
“Let me get four fresh ones.”
“One,” the old man said. His hope and his confidence had never gone. But now they
were freshening as when the breeze rises.
“Two,” the boy said.
“Two,” the old man agreed. “You didn’t steal them?”
“I would,” the boy said. “But I bought these.”
