Proverbs 21:31

The horse [is] prepared against the day of battle: but safety [is] of the LORD.

Ver. 31. The horse is prepared against the day, &c.] A very serviceable creature, and in battle full of terror; so swift in service that the Persians dedicated him to their god, the sun, ασπερ το ταλιστον τω ταχυτατω, as Pausanias hath it. But as the sun in heaven can neither be outrun nor stopped in his race, so neither by men, though wise, nor by means, though likely, can God's purposes be disappointed. "A horse is a vain thing for safety; neither shall he deliver any by his great strength." Psa 33:17

But safety (or victory) is of the Lord.] He gives it to which side he pleaseth, as he did to the Israelites in the conquest of Canaan, though they had no horses to help them, as their adversaries had, and chariots too, both Egyptians and Canaanites.
