'Runner's' in the Bible

He took the commanders of the hundreds and the Carites and the runners and all the people of the land, and they brought the king down from the temple of Yahweh. And they marched by the way of the runner's gate [to] the palace of the king, and he sat on the throne of the kings.

He takes no delight in the strength of a horse, and gains no pleasure in the runner's swiftness.
