In this fast-moving and busy world, to be patient is truly a virtue.
But in a place where it is lacking in water and food, to be patient is really a test of endurance and character.
In the 1st reading, the people travelling through the wilderness lost patience and they spoke against God and Moses.
It was not that there was no food or water, but it was just enough for their sustenance and they were complaining of being sick of the unsatisfying food.
But it was God's turn to lose patience with His people, and He punished them by sending fiery serpents to bite them.
Though God is merciful and compassionate and He forgives us when we sin, let us also not put God to the test.
When we face difficulties in life, instead of complaining and grumbling, let us first be grateful and be thankful for the blessings that we have received from God.
To be aware of God's blessings and to be thankful is indeed a great virtue.
Because it takes humility to be thankful when the going is difficult.
