-Logos. Bible study software. They have a free version. Great place to get started and start building resources for study. You can purchase different upgrade packages and/or one time books, commentaries, etc. I use it weekly.
-New Bible Commentary edited by Gordon J. Wenham, J Alec Moyer, D.A. Carson and R.T. France and their credentials (this is available in Logos). It's a solid overall commentary (in my opinion). I go to commentaries when I need to get someone way smarter than me's take on a passage.
