“יְהוָה, אֱלֹהֵי יְשׁוּעָתִי– יוֹם-צָעַקְתִּי בַלַּיְלָה נֶגְדֶּךָ”
“O YHVH, the God of my salvation, I have cried out by day and in the night before You”
King David used to get up at midnight to study the Torah with Psalms and praises to the King and the Lady, the Shechinah. He expressed the joy of the faith in Malchut and with that revealed the presence of the Shechinah in Malchut.
“וַתָּקָם בְּעוֹד לַיְלָה וַתִּתֵּן טֶרֶף לְבֵיתָהּ וְחֹק לְנַעֲרֹתֶיהָ”
“She rises also while it is still night And gives food to her household And portions to her maidens.”
When we rise to study at midnight, the angels on the upper levels open with joy and praises to the Holy One Blessed Be He. They join those who got up to study and praise God, creating unification of the upper and lower levels.
The Zohar explains that ‘God of my salvation’ relates to the prayer at night is the salvation in the day.
