It's a landmark for a young child to count to 100; it sort of covers all the "ordinary" numbers. One hundred is obviously significant for other groupings: 100 cents is a dollar; 100 yards is a touchdown; 100 years is a century, and the landmark for a very long life. It makes sense, then, that in the Bible, 100 represents fullness or a state of completion, or in some instances simply "much." For instance, people marvel that Abraham had Isaac when he was 100 years old; the number represents the point at which the Lord, when growing up as Jesus, united the human elements of himself with the divine elements and in a sense became "complete.

4243. 'With Laban I have sojourned, and have stayed until now' means that it had taken to itself the good meant by 'Laban'. This is clear from the representation of 'Laban' as intermediate good, that is, good which is not genuine good but nevertheless serves to introduce genuine truths and goods, dealt with in 3974, 3982, 3986 (end), 4063; from the meaning of 'sojourning' as receiving instruction, dealt with in 1463, 2025; and from the meaning of 'staying' or 'staying wish' as that which has reference to the life of truth when accompanied by good, dealt with in 3613, at this point as taking to oneself. From this it is evident that the words 'With Laban I have sojourned, and have stayed until now' mean that it had taken to itself the good meant by 'Laban'.

[2] The implications of all this are as follows: Truth cannot be implanted in good unless means exist to effect this. Those means were the subject in previous chapters, where Jacob's sojourning and staying with Laban, and the flock he acquired there, are referred to. The present chapter deals with the process by which truth and good are joined together, and so with an inversion of state, when order is turned around so that truth is made subordinate to good. Truth seemingly occupies the first position during the time a person is learning truth from an affection for it, though he is not as yet living in accordance with it to any real extent. But good occupies the first position when he does live in accordance with the truth he has learned from an affection for it, for in that case truth becomes good since that person now believes that good consists in acting in accordance with truth. People who are regenerate are governed by this good, as also are those who possess conscience, that is, who no longer reason whether it is the truth but do it because it is the truth, and so who have taken it to themselves in faith and in life.
