창세기 24:63의 주석

לשוח TO MEDITATE — this means “to pray” (Genesis Rabbah 60:14), as we find (Psalms 102:1) “[A prayer of the afflicted …] when he poureth forth his plaint.

ויצא יצחק לשוח בשדה, the word לשוח is basically the same as שיח השדה, “the plants that grow in the field,” (Genesis 2,5). Yitzchok went out to plant useful vegetation, trees, etc., and to check the work of his employees. While he was thus occupied he happened to espy גמלים באים, camels approaching. He came closer to see if per chance they were the camels belonging to his father which the servant Eliezer had been leading.

ויצא יצחק לשוח, he had detoured from his regular path to the field in order to pour out his heart to G’d in prayer. He did not want to be interrupted in his devotion by passing travelers whom he would have to greet. This was in spite of the fact that he had already prayed in Beer lachay Ro-i. His prayer had been answered already, in accordance with Daniel 10,12 מן היום אשר נתת את לבך להבין ולהענות...נשמעו דבריך, “for from the first day you set your mind to get understanding, practicing abstinence before your G’d, your prayer was heard and I have come because of your prayer.”
