In a prophecy given through Amos in the middle of the 8th century BC, God reminds the people of the northern kingdom of Israel of his mighty deeds on behalf of their ancestors. These included the total defeat of the Amorite kings Sihon and Og in year 40 of Israel's time in the wilderness (Num 21; Dt 2-3).
In Amos 2:9, God proclaims, "Yet it was I who destroyed the Amorite before them, whose height was as the height of the cedars and who was as strong as the oaks; I destroyed his fruit above and his roots beneath."
This verse reminds us that there were giants among these Amorites, including Og himself, as Deuteronomy 2 and 3 point out. These giants may have been descendants of Nephilim with connections to evil spiritual forces.
A Jewish tradition recorded in Midrash Tanchuma relates the phrase "his fruit above" to the angelic overseers of the Amorites, and "his fruit beneath" to the Amorites. This tradition also suggests that the battles with the Amorites involved spiritual as well as physical conflict.
That spiritual conflict has continued throughout history. In a sermon at Church of the Messiah on October 24, 2026, Kyle Kettering looked at times when Jesus sent out some of his disciples on mission trips as part of their training as apostles (Mt 10, Mk 6, Lk 10). When Jesus sent them to the towns of Galilee, he "gave them authority over the unclean spirits" (Mk 6:7), and "they cast out many demons" (Mk 6:13).
The disciples reported to Jesus, "Lord, even the demons are subject to us in your name!" (Lk 10:17) Jesus responded, "I saw Satan fall like lightning from heaven" (verse 18).
Kyle noted that Brad H. Young, in his Hebraic Heritage Bible Newer Testament, translates Luke 10:18, "I am watching Satan fall like a flash of lightning from heaven." Kyle explained that the verb tense in Luke 10:18 does not necessarily imply a completed action. Dr. Young's translation communicates the idea that Jesus was not talking in verse 18 about a past event. Instead, the fall that Jesus sees is probably Satan's future and ultimate downfall, as Joel B. Green says in his NICNT commentary on Luke. Green explains, "The decisive fall of Satan is anticipated in the future, but it is already becoming manifest through the mission of Jesus and, by extension, through the ministry of his envoys" (p. 419). The battle against the forces of evil continues as God's Kingdom advances.
