Kabbalah do Samuela II 8:13

"Therefore the Elohim give you of the dew of heaven, and the fatness of the earth, and plenty of corn and wine" (Beresheet 27:28). Rabbi Abba said, This verse has already been explained. Nevertheless, come and look at the verse, "A song of ascent. In my distress I cried to Hashem, and He heard me" (Tehilim 120:1). How many songs and praises did David say before the Holy One, blessed be He, all in order to fix his grade and to make himself a name, as it is written, "And David got him a name" (II Shmuel 8:13). This song he said when he saw what Jacob accomplished, that he was answered and received the blessings. He said, "In my distress I cried to Hashem, and He heard me." [If it were not for Jacob, who received the blessings, the secret of the whole Mochin to construct the Nukva, David could not have made Her a name.]
