Joshua 10: Chapter is all about Israel’s victories in the south over the five kings. The kings are all executed. One question I do have comes from this verse: “Isn’t this written in the Jashar scroll?” (CEB Study Bible, p. 343 OT; Joshua 10.13) What’s the Jashar scroll? According to the notes it is “an ancient source mentioned also in 2 Samuel 1:18. The origin and contents of the scroll are unknown, but apparently it contained at least these two poems and perhaps others” (p. 343 OT).
Joshua 11: We learn about victories in the north. As with the kings of the south, they killed all the kings of the north too.
Joshua 12: According to this chapter, Moses killed the two kings on the east side of the Jordan river and Joseph killed a total of 31 kings on the west side of the Jordan river.
2 Thessalonians 2: This chapter focuses on warning and instruction about the coming of Christ. We learn what things will happen the days before Jesus returns. The author warns us not to be deceived by the lawless people.
