Arcana Coelestia # 3149
3149. 'And [food] was set before him to eat' means that the affection for good in the natural man wished to make Divine things its own. This is clear from the representation of 'Laban', who 'set' the food before him, as the affection for good in the natural man, dealt with in 3129, 3130, and from the meaning of 'eating' as being communicated and made one's own, dealt with in 2187, 2343, that is to say, the Divine things, spoken of above in 3140, 3141.
Bless
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.
