Most birds that I know of are particularly fast & sharp. Birds or their feathers are often a symbol of freedom or pace. Freedom usually means having the ability to break free from the pack. Many birds fly in packs/herds/flocks & put on spectacular displays of precision. Some of the birds that fly in flocks are also slow & cumbersome but glide beautifully like the pelican. Some birds can’t even get off the ground but they can run like the wind. They have legs & know how to use them. Job 39:13-18.
Are not two sparrows sold for a penny? Yet not one of them will fall to the ground outside your Father’s care. And even the very hairs of your head are all numbered. So don’t be afraid; you are worth more than many sparrows. Matt 10:29-31.
While Eshcer may have us thinking about maths,
Scripture & creation can have us turning our thoughts to God.
