4277. 'And he touched the hollow of his thigh' means where celestial-spiritual good is joined to natural good meant by 'Jacob'. This is clear from the meaning of 'the thigh' as conjugial love, and consequently as all celestial and spiritual love, since these are derived from conjugial love as offspring from their parent, dealt with in 3021; and from the meaning of 'the hollow' or socket or cavity of it - that is to say, of the thigh - as the place where the joining together exists, and here therefore where celestial-spiritual good is joined to natural good meant by 'Jacob'. But no one can be told anything about that conjunction unless he knows first of all what celestial-spiritual good, meant by 'Israel', is, and what natural good, meant by 'Jacob', is. It will be told below at verse 28 where Jacob, who at that point is named Israel, is the subject and also further on where Jacob's descendants are the subject.

4278. 'And the hollow of Jacob's thigh was out of joint as he wrestled with him' means that truth did not as yet have the power to join itself completely to good. This is clear from the meaning of 'being out of joint' as a situation in which truths have not yet been arranged into such an order that together with good they could all enter celestial-spiritual good, dealt with in the explanation at verse 31 below. The meaning as a consequence is that truth did not as yet have the power to join itself completely to good, for 'the hollow of the thigh' means the place where different kinds of good are joined together, as stated immediately above in 4277.
