Trees are big in the Torah and Bible generally. The Bible Project did a whole series on trees in the Bible. You've got the Tree of Life, the Tree of the Knowledge of Good and Evil, the cross, the tree in the book of Jonah, the fig tree, the parable of the vine and the branches, etc..

It all makes sense for a religion steeped in a desert culture. Trees are (relatively) rare, and what they offer is incredibly important and life giving.
