'Swift' in the Bible

“They pass by like the [swift] boats made of reeds,Like an eagle that swoops down on its prey.

“Who sent out the wild donkey free [from dependence on man]?And who has loosed the bonds of the wild donkey [to survive in the wild],

“Yet when she lifts herself on high,[So swift is she that] she laughs at the horse and his rider.

“Behind him he makes a shining wake;One would think the deep to be gray-haired [with foam].
