Never look a gift horse in the mouth?

Where on earth did this expression come from? Its such a bizarre thing to say but used so often. I would love to know its origins if anyone has any ideas
In olden times, it was a way of saying don’t inspect the teeth of a horse (the olden time way to do a quick check of a horse’s health and age) when someone has given it to you as a gift. That would bespeak ingratitude of a sort.
