Genesis 27:29

²⁹ And let peoples serve thee, and tribes worship thee: be thou lord of thy brethren, and let they mother's children bow down before thee. Cursed be he that curseth thee: and let him that blesseth thee be filled with blessings.

Genesis 24:4

⁴ But that thou go to my own country and kindred, and take a wife from thence for my son Isaac.

'Isaac' signifies the Lord's interior self and His divine rational in reference to divine good.
