The lion hath roared, who will not fear?.... Amos said this from his own experience, who, having been a herdsman in the wilderness of Tekoa, had often heard a lion roar, which had put him into a panic, both for himself, and the cattle he kept; the figure is explained in the next clause:the Lord God hath spoken, who can but prophesy?
whether it be to foretell future events, which the Lord has made known shall come to pass; or to preach the word, which is to prophesy to edification, to exhortation, and comfort, 1Co 14:3; or to perform the more private exercises of religion, as singing of psalms, praying, &c.
1Ch 25:1; these things who can forbear doing, to whom the Lord has spoken either in a dream or vision, or in his word, and by his Spirit; and to whom he has given a call and commissions, and gifts and graces, qualifying them for such service?
who that has the fear of God in his heart, and his glory in view, and the good of others, that can refrain from it? nay, it is of dangerous consequence to refuse it; for if the roaring of a lion is so terrible, and if the wrath of an earthly king is as the roaring of a lion, much more the wrath and displeasure of the King of kings.
Jonah declined prophesying when the Lord spoke to him, but what was the consequence of it? the prophet by this seems to justify himself in prophesying, and that he ought not to be blamed for it, seeing the Lord had given him the word, and therefore he ought to publish it.
