Amos 7:14-16

14 Then Amos answered and said to Amaziah, 1"I wasa no prophet, nor a prophet's son, but 2I was a herdsman and a dresser of sycamore figs.
15 3But the LORD took me from following the flock, and the LORD said to me, 'Go, prophesy to my people Israel.'
16 4Now therefore hear the word of the LORD. "You say, 5'Do not prophesy against Israel, and 6do not preach against the house of 7Isaac.'
