Jesus’ Preserving and Destroying saying may play off two different senses of the noun נֶפֶשׁ (nefesh, “soul”).
David N. Bivin and Joshua N. Tilton suggest a Hebrew reconstruction of Jesus’ instructions about how the twelve apostles were to behave when they entered a town. In this pericope we learn about the giving and receiving of hospitality among Jesus’ earliest followers. We also learn what may be wrong about the popular view that shaking the dust from the apostles’ feet was a symbolic action meant to signal to Jews who rejected Jesus that they were henceforth to be considered as Gentiles.
“Wheresoever the body is, thither will the eagles be gathered together” (Luke 17:37; KJV), is certainly one of the most enigmatic of Jesus’ sayings. Commentators have noted that Jesus employed a proverbial saying to reply to his disciples’ question; however, they differ about what the proverb means in this context.
