Reminds of an interesting footnote from Bishop Challoner to another seemingly random detail:
Tob. 11:9 Then the dog, which had been with them in the way, ran before, and coming as if he had brought the news, shewed his joy by his fawning and wagging his tail.
9 “The dog”… This may seem a very minute circumstance to be recorded in sacred history: but as we learn from our Saviour, St. Matt. 5. 18, there are iotas and tittles in the word of God: that is to say, things that appear minute, but which have indeed a deep and mysterious meaning in them.
