Isaiah 8:1, 3-4

Then the LORD said to me, “Take for yourself a large tablet [for public display] and write on it in ordinary characters: Belonging to Maher-shalal-hash-baz.

So I approached [my wife] the prophetess, and she conceived and gave birth to a son. Then the LORD said to me, “Name him Maher-shalal-hash-baz [to remind the people of the prophecy]; for before the boy knows how to say, ‘My father’ or ‘My mother,’ the riches of Damascus (Aram’s capital) and the spoil of Samaria (Israel’s capital) will be carried away by the king of Assyria.”
