Judges 19:22 change wording from "we can sleep with him" to what you see. Under these violent circumstances, to "sleep" would be impossible so it is better to be more explicit. The Hebrew says, "to know" which is euphemism for the sex act.
Judges 19:20 change wording from, "I wish that things will go well for you, but I would like to provide what you need" to what you see. This fits better with the text and the idea of the old man's benediction.
