3137. 'At the spring' means the enlightenment of them from Divine truth. This is clear from the meaning of 'a spring' as truth, dealt with in 2702, 3096, here Divine truth, as above in 3131. Because the Word is Divine truth it is therefore called 'a spring'. That 'standing at the spring' here embodies in the internal sense the enlightenment of things in the natural man follows from the train of thought; for where Divine truth is, enlightenment is there.

The basic meaning of "follow" in the Bible is pretty obvious if we consider what it means to "follow the Lord." That obviously doesn't mean we're going to wait for Him to go for a walk and tag along; it means we're going to do the things He said and believe the things He tells us in the Bible. We're going to follow Him by making His precepts a part of our lives. That same idea applies to other cases. When people in the Bible follow something, it means they are making that spiritual thing (whatever spiritual thing is described) a part of their lives. And the order of the language can even be reversed: sometimes things are described as following people (as in Psalm 23: "surely goodness and mercy will follow me..."), which again means that people are making those spiritual qualities a part of their lives.
