2 Samuel 13:29

And the servants of Absalom did unto Amnon as Absalom had
commanded
They smote him, and killed him, when he gave the word:

then all the king's sons arose;
from the feast, imagining they were all designed to be slain:

and every man gat him up upon his mule, and fled;
creatures much used in Judea instead of horses, which, though they might not be bred, might be used ^F15.
