Shared ground
Amos presents his authority as coming from a direct call from Yahweh, not from a recognized religious career path. In his own words, he was not a “prophet” as a settled role and not a “prophet’s son,” but a rural worker (herding and sycamore-fig work). Then Yahweh “took” him from his flock and gave a clear commission: “Go, prophesy to my people Israel” (Amos 7:14–7:15).
These verses also assume a basic distinction between (1) social recognition or professional identity and (2) divine commissioning. Amos grounds his message in the second.
Where interpretation differs
Two phrases carry most of the uncertainty.
“Not a prophet … not a prophet’s son”: Some read this as Amos denying he ever belonged to any prophetic “guild” or recognized circle. Others read it more narrowly: he is denying that he was a professional prophet (someone who earns his living this way) or that he comes from an inherited prophetic household, without denying that he is truly a prophet now.
“Yahweh took me”: Some think “took” suggests a strong seizure or compulsion; others think it simply means appointment—Yahweh selected him and redirected his life.
Why the disagreement exists
The wording is brief and can fit more than one social picture. “Prophet’s son” can mean a literal family connection or a member of a prophetic circle, and “no prophet” can sound like a denial of identity unless it is heard as “not a prophet by trade.” Likewise, “took” can describe anything from firm intervention to straightforward selection.
What this passage clearly contributes
Explicitly, the text claims: Amos answers Amaziah, denies a standard prophetic pedigree, identifies himself as a herdsman and sycamore worker, and says Yahweh redirected him and commanded him to prophesy to Israel. Theological inference that follows naturally is that prophetic authority (in this scene) is tied to Yahweh’s commissioning rather than institutional endorsement or personal career ambition, and that Yahweh may call someone from outside expected social pathways.
