Judges 19:16

And, behold, there came an old man from his work out of the field at even, which was also of mount Ephraim; and he sojourned in Gibeah: but the men of the place were Benjamites.

There came an old man from his work ... which was also of mount Ephraim - and perhaps his hospitality was quickened by learning the stranger's occupation, and that he was on his return to his duties at Shiloh.
