6027. 'And he sent Judah before him to Joseph' means a communication of the good of the Church with the internal celestial. This is clear from the representation of 'Judah' as the good of the Church, dealt with in 5583, 5603, 5782, 5794, 5837; and from the representation of' Joseph' as the internal celestial, dealt with in 5869, 5877. And 'sending before him', it is self-evident, means communicating. The reason why Judah and not anyone else was sent was so that a direct communication of good with good might be denoted, that is, a direct communication of external good, which 'Judah' represents, with internal good, which 'Joseph' represents. For good that is the good of love to the Lord and charity towards the neighbour flows in from Him by way of the internal into the external, the amount of good in the external determining how much is received there. But if merely the truth of faith and no good is present in a person's external, the inflow of good from the Lord by way of the internal cannot be received in the external. For no direct communication with truth can exist there, only an indirect one through good. This is why Judah and not anyone else was sent from Jacob to Joseph.

9783. 'To cause a lamp to go up continually' means faith from there, and through that faith an intelligent understanding of truth and a wise discernment of good from the Lord. This is clear from the meaning of 'a lamp' as faith, and from this an intelligent understanding of truth and a wise discernment of good, dealt with in 9548. 'A lamp' means faith because Divine Truth emanating from the Lord composes the light in heaven. This light when received by the angels there, or by a person in the world, resembles a lamp; for it casts light into all parts of the mind and imparts intelligence and wisdom. This light so received is faith. But it should be remembered that faith is not a lamp or that which casts light into the mind unless it is fed by charity, and so unless it is charity. The situation with faith and charity is the same as it is with truth and good. Just as truth is the outward form of good, or good embodied in an outward form, enabling it to be seen in light, so faith is the outward form of charity, or charity embodied in an outward form. Faith furthermore is that to which truth belongs, and charity is that to which good belongs. For truth, when believed, passes into faith; and good, when loved, passes into charity. The good and truth themselves that are loved are the neighbour, and the love of the neighbour is charity.
