If he is not able to bring a lamb, then he shall bring to the LORD, for his trespass which he has committed, two turtledoves or two young pigeons: one as a sin offering and the other as a burnt offering.
Le 5:7
Why did Mose let them offer two offerings? Why does a sin offering not enough? What is the meaning of burnt offering here?
Sorry, I don't have time to do research and so I put my question here.
