3852. And served with him yet seven other years. That this signifies holy study is evident from the signification of “serving,” as being study (see n. 3824, 3846), and from the signification of “seven,” as being what is holy (n. 395, 433, 716, 881, 3824). That is called holy study through which internal truths are conjoined with good, for all internal truths look to the Lord, and are conjoined through love to Him, this love being holiness itself.

3846. And we will give thee her also, for the service which thou shalt serve with me yet seven other years. That this signifies that then there would be a full state of study, is evident from the signification of “service” and of “serving,” as being study (see n. 3824); and from the signification of “seven years,” as being the same as a “week,” namely, a state and an entire period, as above (n. 3845); thus a full state, which is also holy (n. 3824). This expression, “we will give thee her also,” signifies that then there would be conjunction with the affection of internal truth. The reason why in the internal sense “serving” is study, is that the labor of the external man is study in the internal man. Hence study is called a labor of the mind.
