'Sparrows' in the Bible

Aren’t two sparrows sold for a penny? Yet not one of them falls to the ground without your Father’s consent.

So don’t be afraid therefore; you are worth more than many sparrows.

Aren’t five sparrows sold for two pennies? Yet not one of them is forgotten in God’s sight.

Indeed, the hairs of your head are all counted. Don’t be afraid; you are worth more than many sparrows!
