3129. 'And Rebekah had a brother' means the affection for good in the natural man. This is clear from the meaning of 'a brother' and of 'a sister' in the Word - 'a brother' being the affection for good, and 'a sister' the affection for truth, dealt with in 367, 2360, 2508, 2524. For in the natural man, as in the rational, all things there are interrelated like blood relatives and relatives by marriage, 2556, 2739. For that reason also the rational mind as well as the natural mind is called a house or family where parents, brothers, sisters, blood relatives, and relatives by marriage exist in order.

The Lord in essence is perfect love expressed as perfect wisdom. He created us so that He could love us, give us love and wisdom of our own, and thus be united with us. This is the ultimate blessing, for us to receive His love and wisdom and to be together with Him, and all other forms and meanings of "blessing" flow from it. This flow, however, takes many different forms in the Bible. When people receive the Lord's blessing, it illustrates how His love and wisdom flow into us in forms that fit the spiritual state people represent in the Word. When people bless the Lord, it indicates an acknowledgment that life and all its gifts come from Him and shows a desire to accept them and be conjoined. When people bless each other, it represents the desire to share good desires and true ideas as much as possible.
