Habakkuk 3:9-11

He calls them too the oaths to the tribes: for though God had spoken to Abraham and afterwards to Moses, yet the promise was deposited in the hands of Abraham, and of the patriarchs, and afterwards in those of Moses, that the people might understand that it belonged equally to them; for it would have been no great matter to promise what we read of to a few men only. But Abraham was as it were the depository; and it was a certain solemn stipulation made with his whole race. We hence see why the Prophet here mentions the tribes rather than Abraham, or the patriarchs or Moses. He had indeed a special regard to those of his own time, in order to confirm them, that they might not doubt but that God would extend to them also the same power. How so? Because God had formerly wrought in a wonderful manner for the deliverance of his people. Why? That he might prove himself to be true and faithful. In what respect? Because he had said, that he would be the protector of his people; and he did not adopt a few men only, but the whole race of Abraham. Since it was so, why should not his posterity hope for that which they knew was promised to their fathers? for the truth of God can never fail. Though many ages had passed away, the faith of his people ought to have remained certain, for God intended to show himself to be the same as he had been formerly known by their fathers.

He afterwards adds אמר, amer, which means a word or speech; but it is to be taken here for a fixed and an irrevocable word. The word, אמר, amer, he says; that is, as they say, the word and the deed: for when we say, that words are given, we often understand that those who liberally promise are false men, and that we are only trifled with and disappointed when we place confidence in them. But the term, word, is sometimes taken in a good sense. “This is the word,” we often say, when we intend to remove every doubt. We now then perceive what the Prophet meant by adding אמר, amer, the word. “O Lord, thou hast not given mere words to a people; but what has proceeded from thy mouth has been found to be true and valid. Such, therefore, is and faithfulness in thy promises, that we ought not to entertain the least doubt as to the event. As soon as thou givest to us any hope, we ought to feel assured of its accomplishment, as though it were not a word but the exhibition of the thing itself.” In short, by this term the Prophet commends the faithfulness of God, lest we should harbour doubts as to his promises.

He then says, that by rivers had been cleft the earth. He refers, I doubt not, to the history we read in Numbers 14; for the Lord, when the people were nearly dead through thirst, drew forth water from the rock, and caused a river to flow wherever the people journeyed. As then he had cleft the earth to make a perpetual course for the stream, and thus supplied the people in dry places with abundance of water, the Prophet says here, that the earth had been cleft by rivers or streams. It was indeed but one river; but he amplifies, and justly so, that remarkable work of God. He afterwards adds—
