'Outward Appearance' in the Bible

So she took off her mourning apparel, covered herself with a shawl, and concealed her outward appearance. Then she went out and sat at the entrance of Enaim, which is on the way to Timnah, because she knew that even though Shelah had grown up, she wasn't being given to him as his wife.

The LORD told Samuel, "Don't look at his appearance or his height, for I've rejected him. Truly, God does not see what man sees, for man looks at the outward appearance, but the LORD sees the heart."

There was spread out over the heads of the living beings what looked like a canopy, in outward appearance resembling ice,

"Indeed, the LORD God of Israel says that he hates divorce, along with the one who conceals his violence by outward appearances," says the LORD of the Heavenly Armies. "So guard yourselves carefully, and don't be unfaithful."

Now those who were reputed to be important added nothing to my message. (What sort of people they were makes no difference to me, since God pays no attention to outward appearances.)
