The Creator of the Universe, on the subject:
Matthew 6
1 "Be careful not to do your 'acts of righteousness' in front of others, to be seen by them. If you do, you will have no reward from your Father in heaven.
2 "So when you give to the needy, do not announce it with trumpets, as the hypocrites do in the synagogues and on the streets, to be honored by others. Truly I tell you, they have received their reward in full. 3 But when you give to the needy, do not let your left hand know what your right hand is doing, 4 so that your giving may be in secret. Then your Father, who sees what is done in secret, will reward you.
The same Individual, on the subject of "as G-d has shown us, by turning stones to bread.."
Matthew 4
1Then Jesus was led by the Spirit into the desert to be tempted by the devil. 2After fasting forty days and forty nights, he was hungry. 3The tempter came to him and said, "If you are the Son of God, tell these stones to become bread."
4Jesus answered, "It is written: 'Man does not live on bread alone, but on every word that comes from the mouth of God."
