Matthew Poole and continuators on Amos 3:8

8 The lion hath roared , who will not fear ? the Lord GOD hath spoken , who can but prophesie .

God hath threatned, and as a Lion roareth when near his prey; so God hath terribly threatned what is near to be done; Amos lived and prophesied in Ieroboams time about the 3150th year of the World, and these threatned judgments began to come upon Israel, when the conspiracies and usurpations of Shallum, Menahem, &c. filled all with blood and confusions about 3177th year of the world.

What wise man, who that is solicitous for his own good and safety, or that hath any affections for the good of others, will do less than reverence and fear, and prevent by a speedy repentance.

This is plainly what was before figuratively set forth, God had spoken to his Prophets but dreadful things against Israel.

They dare not conceal them, Amos cannot but speak what he had heard. Ier. 1.17. Acts 4.19. and 5.25.
