John Trapp on Habakkuk 3:9

Verſe 9. Thy bowe was made quite naked] ſc. Out of the caſe. He meaneth, thy power was clearly manifeſted, and powerfully exerted againſt the nations above mentioned: ſo that all men might ſee plainly, that thou wert that man of warre, Exod. 15.3. which ſhooteſt thine arrowes at a certainty, and never miſſeſt thine enemies, thy but-mark. See Job 16.12.

according to the oathes of the tribes, even thy word] i. e. according to thy promiſes to thy people, confirmed with oathes, even thoſe ſure mercies of David, or aſſured to David. Some render it, according to the oathes, thoſe props of thy word. His word is ſure and ſufficient of it ſelf: but, for our better ſettlement, and as a prop to our faith, He hath bound it with oathes: that by two immutable things, in which it was impoſſible for God to lie, we might have ſtrong conſolation, Heb. 6.18. For now we may ſay with Solomon, For thy words ſake, nay more, For thine oathes ſake, and according to thine own heart haſt thou done all this, 2 Sam. 7.18, 21. Thy love moved thee to make promiſe, yea, to give oath: and now thy truth bindeth thee to performe. All thy pathes to thy people now are mercy and truth, Pſal. 25.10. not mercy onely, but mercy and truth: not by a providence onely, but by vertue of a promiſe, ratified with an oath: This is ſweet indeed; this deſerves a Selah] to be ſet to it.

thou didſt cleave the earth with rivers] Exod. 17.6. Pſal. 78.15, 16. Deut. 8.15. Neh. 9.15. This cleaving the hard Rock, and ſetting it abroach, this turning of the flint into a fountain, Pſal. 114.8. was a work of Omnipotency, and is therefore ſo much celebrated. It maketh much to the miracle, that the earth was cleft with rivers: this importeth both the plenty and the perennity thereof: for the Rock, that is, the river out of the rock followed them, 1 Cor. 10.4. leſt in that dry and barren wilderneſſe they ſhould periſh for want of water. The ſame God alſo who had given his people petram aquatilem, gave them pluviam eſcatilem, Tertul. de patientia. (as Tertullian phraſeth it) Manna from heaven, Quails in great abundance, and never was Prince better ſerved in his greateſt pomp. He alſo defended them from the fiery ſerpents, and delivered them from a thouſand other deaths, and dangers: all which mercies are here implied, though one onely be inſtanced: and all to aſcertain the Saints how much God ſetteth by them, and what he will yet do for them, as occaſion requireth. As he made the world at firſt, that he might communicate and impart himſelf to his Elect: ſo for their ſakes doth he ſtill preſerve and govern it, ordering the worlds diſorders by an over-ruling power, for his own glory, and their eternall good.
