An illustration from the Second Book of Kings, in the Holy Bible, about being over-welcoming of strangers.
“Then Isaiah the prophet went to King Hezekiah and asked, “What did those men say, and where did they come from?” “From a distant land,” Hezekiah replied. “They came from Babylon.”
“The prophet asked, “What did they see in your palace?” “They saw everything in my palace,” Hezekiah said. “There is nothing among my treasures that I did not show them.”
“Then Isaiah said to Hezekiah, “Hear the word of the Lord: The time will surely come when everything in your palace, and all that your predecessors have stored up until this day, will be carried off to Babylon. Nothing will be left, says the Lord.”
“And some of your descendants, your own flesh and blood who will be born to you, will be taken away, and they will become eunuchs in the palace of the king of Babylon.”
“The word of the Lord you have spoken is good,” Hezekiah replied.”
“For he thought, “Will there not be peace and security in my lifetime?”
2 Kings 20:14-19
