Mattityahu 2:12-13

And having been warned in a chalom (dream) not to return to Herod, they took refuge in their own country by another way. And when they had gone — hinei! — a malach HASHEM appeared to Yosef in a chalom (dream), saying, Arise, and take the yeled and his Em, and flee to Eretz Mitzrayim (Egypt), and stay there until I tell you, for Herod is about to seek the yeled to destroy him.
