'Given to the Poor' in the Bible

for this might have been sold for much and been given to the poor.

for this ointment could have been sold for more than three hundred denarii and given to the poor. And they spoke very angrily at her.

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

according as it is written, He has scattered abroad, he has given to the poor, his righteousness remains for ever.
