Kabbalah do Psalmów 120:1

"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.]

Rabbi Elazar said, It was Jacob who sang this song, when his father said to him, "Come near, I pray you, that I may feel you, my son, whether you are really my son Esau or not" (Beresheet 27:21). Then was Jacob in great distress, for he feared that his father will recognize and know him. Then it is written, "and he recognized him not, because his hands were hairy, as his brother Esau's hands, so he blessed him" (Beresheet 27: 23). So he said, "In my distress I cried to Hashem, and He heard me."
