'Grain Offering' in the Bible

So Manoah prepared a young goat and a grain offering and offered it on a boulder to the LORD, who kept on performing miracles while Manoah and his wife watched continually.

But his wife replied to him, "If the LORD had intended to kill us, he wouldn't have accepted a burnt offering and a grain offering from us, he wouldn't have shown us all these things, and he wouldn't have permitted us to hear things like this, now would he?"
