Two books that I recommend for learning how to preach and teach are (1) Biblical Preaching: The Development and Delivery of Expository Messages. Haddon Robbinson. Grand Rapids, MI: Baker Academic, 2001, and (2) Invitation to Biblical Preaching: Proclaiming Truth with Clarity and Relevance. Donald Sunukjian. Grand Rapids, MI: Kregel, 2007.

When it comes to understanding the broader themes of Scripture, I highly recommend this set of books, written by one of my professors: A Systematic Theology of Biblical Christianity. 3 Volumes. Rolland McCune. Allen Park, MI: Detroit Baptist Theological Seminary, 2010. 

A great cross-reference resource for finding passages with similar thoughts to the passage that you are studying is in R.A. Torrey’s The Treasury of Scripture Knowledge. This book is in the public domain.

I cannot keep up with the amazing Bible software that Christians have created to aid Bible study, but here are at least two that can be installed on a computer or on your smartphones via their apps. (1) Logos: https://www.logos.com/ – I use Logos all the time, but it requires a good deal of money over the long haul to purchase resources. They have a vast website, however, complete with a trove of videos to teach you how to use the program. (2) e-Sword: https://www.e-sword.net/ – e-Sword is another platform that allows you to download and add many resources, especially a trove of public domain resources. If you have limited funds, this resource is especially helpful. I used this platform during college and discovered Logos in my seminary days. 

Commentaries: “Detroit Baptist Theological Seminary Book List” and “850 Books for Bible Expositors by The Master’s Seminary” are two helpful lists, and links to both can be found at https://davidhuffstutler.com/book-recommendations/

Don’t get overwhelmed by the above. If you are just beginning to teach or preach in your church and have only one to two hours to prepare each week, here is what I would recommend: (1) Read How to Read the Bible for All Its Worthand Biblical Preaching. (2) Study the passage to the best of your ability. (3) Use the MacArthur Study Bible and its notes to help understand your passage better. (4) Use e-Sword and whatever sound resources it provides to help you study your passage further. If you don’t mind spending some money, buy Logos. (5) Prepare well, and make the most of your teaching opportunity. (6) Make use of your pastors. Ask them about your passage and check your conclusions. Having asked you to assist in teaching the Word, I would hope that they would be glad to help you rightly divide the truth among the flock that they shepherd!
