In keeping with the international character of the series, E. John Hamlin's commentary on Joshua pays more than usual attention to the fulfillment of the third part of God's promise to Abraham, “By you all the nations of the earth shall bless themselves,” as well as to the roles played by non-Israelites such as Rahab and the Gibeonites. Hamlin also takes full account of issues such as war and liberation, and distribution and management, and personal fulfillment.

Among the important theological insights revealed in this commentary are God's faithfulness to his oppressed people, the importance of land to the covenantal idea, the establishment of a new society based on justice, freedom, and loyalty and secured through covenant teaching and covenant bonding, and kingdom struggles leading to kingdom victory and pointing to God's final victory.
