Isaiah 7:11

“When Pharaoh speaks to you, saying, ‘Work a miraculous wonder,’ then you shall say to Aaron, ‘Take your staff and throw it down before Pharaoh, that it may become a serpent.’”

“Now this shall be the sign to you from Yahweh, that Yahweh will do this word that He has spoken:

‘This will be the sign to you,’ declares Yahweh, ‘that I am going to punish you in this place, so that you may know that My words will surely be established against you for evil.’

The word of Yahweh which came to Hosea the son of Beeri, in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah, and in the days of Jeroboam the son of Joash, king of Israel.

The word of Yahweh which came to Micah of Moresheth in the days of Jotham, Ahaz, and Hezekiah, kings of Judah, which he beheld concerning Samaria and Jerusalem.

“And this will be the sign for you: you will find a baby wrapped in cloths and lying in a manger.”
