Musar su Genesi 12:9

The message in our case is that Abraham's entire striving from then on was to achieve a position on the right side of G–d. He constantly moved in a spiritually "southward" direction, i.e. striving to come closer to G–d. This is expressed in the Torah by the words 12,9) הלוך ונסוע הנגבה). He achieved his goal: though he sat on G–d's left side, G–d portrayed Himself as sitting on Abraham's right side. Performance of acts of kindness, charity, hospitality, etc. are all expressions of drawing people near with one's right hand, i.e. a symbolic way of expressing one's desire to sit on the right side of G–d. All of the Messiah's eventual accomplishments are merely an extension of a process that Abraham had set in motion, a process of drawing near to G–d. This is the reason that Psalm 110 which the Yalkut quoted commences with words indicating that G–d invites Abraham to sit on His right, meaning that since Abraham had activated G–d's "right," the position of David (the Messiah on G–d's right side) is due to Abraham's accomplishments.
