When Jacob heard there was grain in Egypt, he sent our ancestors the first time.

When they had eaten enough, they began to lighten the ship by throwing the grain overboard into the sea.

For the hearts of these people
have grown callous,
their ears are hard of hearing,
and they have shut their eyes;
otherwise they might see with their eyes
and hear with their ears,
understand with their heart,
and be converted,
and I would heal them.
