Amos 7:14-16

14Then answered Amos, and said to Amaziah, I was no prophet, neither was I a prophet’s son; but I was an herdman, and a gatherer of sycomore fruit:1 15And the Lord took me as I followed the flock, and the Lord said unto me, Go, prophesy unto my people Israel.2

16Now therefore hear thou the word of the Lord: Thou sayest, Prophesy not against Israel, and drop not thy word against the house of Isaac.
