Two great resources that I used with my students when I had them do Exegesis Papers were:
New Jerome Biblical Commentary (a classic)
http://www.amazon.com/New-Jerome-Biblical-Commentary/dp/0136149340/ref=sr_1_1?ie=UTF8&qid=1444197951&sr=8-1&keywords=new+jerome
and
The New Jerome Bible Handbook (based on the Commentary, but valuable in itself)
http://www.amazon.com/Jerome-Bible-Handbook-Biblical-Commentary/dp/0814622046/ref=sr_1_2?ie=UTF8&qid=1444197951&sr=8-2&keywords=new+jerome
While Verbum has an incredible amount of commentaries, I would love to see these added!
