Kabbalah zu Tehillim 147:11

"Then Pharaoh sent and called Joseph, and they brought him hastily out of the dungeon." Rabbi Abba opened the discussion with the verse, "Hashem takes pleasure in those who fear Him, in those who hope for His mercy" (Tehilim 147:11). How much the Holy One, blessed be He, delights in the righteous, for they make peace above, they make peace below, and they bring the bride to her husband. The Holy One, blessed be He, is therefore pleased with those who fear Him and abide by His wish.

And as it says in the Zohar in Miketz. 33. “Those who hope for His mercy.” HE ASKS: Who are “those who hope for His mercy?” HE ANSWERS, They are the ones who study the Torah at night and join the Shechinah. When morning comes, they hope for His mercy.
