Midst

2:9 And out of the ground made the LORD God to grow every tree that is pleasant to the sight, and good for food; the tree of life also in the midst of the garden, and the tree of knowledge of good and evil.

In the last verse, "God planted a garden" and "put the man" there.  Here he's making the plants grow in the garden.  So, "plant" in the last verse really seems specifically to mean "plant seeds", which grow in this verse.  Still, "made ... to grow" is an odd construct.  That's pretty much what happens after you plant seeds in good soil; you don't usually make much effort.

As a computer programmer, I'm tempted to interpret this as: Consider all species of trees.  Some are good looking and have nutritional fruit; some are one or the other; and some are neither.  What grew in the garden were both.  In addition to those, there were (at least) two species that were not both: the tree of life and the tree of knowledge.

Of course, I know that nobody speaks English (or any real language) the way we program computers, so the interpretation is more like:  Consider all species of trees.  Some are good for gardens because they look good; others are convenient to have around because they have nutritional fruit.  (And there may be some overlap betweeen those two sets.)  Most of these species were in the garden.  Also, there were two particularly important trees in the garden that I want to mention, Life and Knowledge.

The "every tree..." business makes this really sound like the fantasy of a farmer.

It's not entirely clear here what the two special trees are about, the tree of life, and the tree of knowledge of good and evil.  But one thing is clear is that it's not "knowledge of mathematics" or "knowledge of sports trivia" or "knowledge of farming techniques" but "knowledge of good and evil".  It's not clear whether that means knowing the difference, or knowing lots of stories about each.

Technically the "in the midst" means close to the middle; in practice, it at least means "not on the edge".  Here it only clearly applies to Life; Knowledge may or may not be near an edge.

Oh, another "LORD God".  This chapter uses that very consistently.
