Good books for understanding literary form of NT epistles?

[CAStratman]

Hello. Could anyone recommend some books or resources for understanding the literary/rhetorical style of the NT epistles, particularly how Paul/Peter/James/Jude use tropes and devices to form their arguments? Something that would help me teach the letters to middle and high school students in a Christian classical school context.

New Testament Rhetoric by Witherington! This is like his thing.
I know his commentaries on the General Epistles are highly regarded by Ligonier.
