'Alert' in the Bible

When he sees chariots, teams of horses, riders on donkeys, riders on camels, he must be alert, very alert."

The sovereign Lord has given me the capacity to be his spokesman, so that I know how to help the weary. He wakes me up every morning; he makes me alert so I can listen attentively as disciples do.

Their horses are faster than leopards and more alert than wolves in the desert. Their horses gallop, their horses come a great distance; like a vulture they swoop down quickly to devour their prey.
