4291. In the internal historical sense, by he said unto him, What is thy name? And he said Jacob, is signified that they were the posterity of Jacob with their quality. This is evident from the signification of a “name,” as being quality (see n. 144, 145, 1754, 1896, 2009, 2724, 3006); and from the signification of “Jacob,” as being his posterity (see n. 4281).

3006. These are the things the angels perceive when “Jesus Christ” is named; and this is what is meant when it is said that there is salvation in no other name, as also by the Lord so often speaking of His “name.” As in John:

Whatsoever ye shall ask in My name, that will I do (John 14:13).

In the same:

These things are written that ye may believe that Jesus is the Christ, the Son of God; and that believing ye may have life in His name (John 20:31); and in other places.

That the “name” is all in one complex by which the Lord is worshiped, and thus denotes the quality of all worship and doctrine, may be seen above (n. 2724); and therefore here it denotes the good of love and of charity conjoined with the truth of faith, which is the complex of all doctrine and of all worship.
