'Sparrows' in the Bible

Do not two sparrows sell for a halfpenny? Yet not one of them will fall to the ground without your Father's leave.

Away then with fear; you are more precious than a multitude of sparrows.

Are not five sparrows sold for a penny? and yet not one of them is a thing forgotten in God's sight.

But the very hairs on your heads are all counted. Away with fear: you are more precious than a multitude of sparrows.'
