In Genesis 43:7, regarding the tenor or tone of Joseph's words to his brothers -- 'telling' in the spiritual sense means discerning; and 'according to the tenor of his words' means that his tone or, literally "mouth", was in accord with the wish to discern.

In Exodus 34:27, being in accord with the "tenor" or "mouth" of Jehovah's words of His covenant, means being joined through these truths. In this instance, it means that by means of information concerning the primary truths to be remembered, there will be conjunction with people in external and internal worship. (Arcana Coelestia 10682-10683)

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.
