'Given to the Poor' in the Bible

For this could have been sold for much, and given to the poor.

For this ointment could have been sold for more than three hundred denarii, and given to the poor. And they murmured against her.

Why was not this ointment sold for three hundred denarii, and given to the poor?

as it is written: He has scattered abroad; he has given to the poor; his righteousness remains forever.
