Chasidut su Salmi 124:1

And this is, "Bless G-d, all servants of G-d, who rise in G-d's house at nights" (Ps. 124:1); specificallt 'who rise at nights', for rising at night to study Torah and pray is the main rectification, for that is how we bind night with day, disorder with order, which is the main rectification of all worlds. This is the juxtaposition of 'Raise your hands in holiness and bless G-d': 'raise your hands', for elevating and binding night with day, disorder with order, is accomplished specifically by the hands, the tools of action, the totality of the Torah. They raise all worlds to their root, as in, 'Raise your hands in holiness and bless G-d', as in, "When I raise my hand to heaven" (Deut. 32:40), which is the raising of the hands spoken about in the Zohar, for the totality of all worlds are held in the hands, as in, "My hand founded the earth and my right hand measured the heavens" (Isaiah 48:13). Therefore, holiness is mainly in the hands, for by fulfilling the Torah and the mitzvot that are held in the hands, the tools of action, we elevate all worlds, which represent disorder, raising and bringing them back to their source, to G-d, to order, represented by wisdom, which is called holiness, as is known. And this is, 'raise your hands with holiness' and it connects well with the previous verse, 'Bless G-d, all G-d's servants, who rise at nights'
