'Show' in the Bible

“I am going the way of all the earth. Be strong, therefore, and show yourself a man.

But show kindness to the sons of Barzillai the Gileadite, and let them be among those who eat at your table; for they assisted me when I fled from Absalom your brother.

Now it happened after many days that the word of the Lord came to Elijah in the third year, saying, “Go, show yourself to Ahab, and I will send rain on the face of the earth.”

So Elijah went to show himself to Ahab. Now the famine was severe in Samaria.

Elijah said, “As the Lord of hosts lives, before whom I stand, I will surely show myself to him today.”
